What's the Best Bottle Cutter on the Market? We Find Out

We review the top five glass bottle cutters to find out which is best.

Four years ago, I threw out the question: "What is the best bottle cutter on the market?" A lot of readers weighed in. Some gave recommendations for their favorite glass bottle cutter, others just wanted a definitive answer, which is what I wanted. Finally, FINALLY, we decided to get to the bottom of the bottle cutter question and have a product shoot out between four popular models. Our competition has not been without a little drama, as one of the bottle cutter makers has, apparently, gone out of business since the inception of this review. That being the Bindu Studio's Bottle Cutter. We've decided to leave the Bindu in the review just in case some of you stumble upon one secondhand. That being said, it's time to introduce each of our competitors (and their final grades):


Long story short: Ephrem's Bottle Cutter Kit received the highest grade, but Creator's Bottle Cutter also worked well. The reviews below should help you choose the cutter which will work best for your needs.  Watch below to see Ephrem's Bottle Cutter in action:

Diamond Tech Craft G2 Glass Bottle Cutter

First to go under the magnifying glass is the Diamond Tech Craft G2 Bottle Cutter, or G2 for short. For such a simple contraption, its assembly was not very intuitive. I would describe it as 'fussy.' By far, it took the longest to assemble of all of our competitors.

Besides the individual pieces, the G2 came with a 'clinker' to insert inside bottles to help their separation by 'tapping' them. This is not something I'd recommend, even with a tapper on hand! It also came with 2 pieces of emery cloth and one cutting head.

Eventually, the assembly was finished:

Setting it up to score was easier than I thought it was going to be. All it took was a few adjustments of the upper arm and lower arm to get the device perpendicular to the bottle, which is imperative to get a proper score.

The setup resulted in a very nice looking, even cut:

Photo: DIY Maven

I used the hot then cold water bath means of separation, which the instructions for the G2 recommends, and it was a huge fail.

Photo: DIY Maven


I tried a second time and achieved another nice cut:

Photo: DIY Maven

But it resulted in another bad break:

Photo: DIY Maven

Would the 3rd time, with a different type of bottle, be the charm? 

Photo: DIY Maven


Nope. In this case multiple hot/cold baths didn't separate the bottle, so I tried the candle flame/cold water method. Still no separation.

Photo: DIY Maven

Okay, if the 4th attempt didn't work, I was going to give up. As it turned out, I got a perfect cut with hot/cold water separation:

Photo: DIY Maven


Because of the design of the G2, bottles with wide mouths require their lids to be intact. That's because you have to punch a hole in the lid to slip the top of the cutter into. I gave that a try with a frappuccino bottle, with bad results. This is because it's very difficult to punch a smooth hole into the exact center of a metal lid. Not doing so means a wavy score line:

Photo: DIY Maven

And then, after all that jockeying with top of the cutter and trying to keep it stable, this happened (I glued it back together and forged ahead):

Photo: DIY Maven

Now, the G2's instructions say that it can cut a bottle on its rounded edges, so I thought I'd give it a try.  This is where all those fussy adjustments came in handy. First, I tried it on the neck:

Photo: DIY Maven

I got a nice cut, but the separation was a huge failure:

Photo: DIY Maven

That last one was a thick champagne bottle, so I thought I'd try something thinner. In this case, a Bloody Mary Mix bottle:

Again, I got a nice cut, and a nearly successful separation. At this point, it was time to move on to our next competitor.

The Bindu Glass Bottle Cutter

The Bindu. It came with a LOT of parts to assemble and although it was a bit time consuming, it went together easily: 

Bindu bottle cutter review
Photo: DIY Maven

What impressed me about it was its solid construction. Steel threaded rod, wing nuts, and hex nuts; 1/8 aluminum brackets; rubber feet, and nylon (or possibly UHMW) rollers all added up to a hefty unit. Also, the cutting head on the Bindu has 6 (!) numbered cutting wheels, so you can keep track of which ones you've used when the old one gets dull. 

Photo: DIY Maven


Setting up the Bindu for scoring was a no-brainer. Just adjust the bracket with the cutting wheel to the length at which you want to cut your bottle and away you go. 

Photo: DIY Maven

My first attempt resulted in a nice cut:

Photo: DIY Maven

Separation with candle/cold water, as suggested by Bindu's instructions, wasn't a total failure, but it wasn't good either.

Photo: DIY Maven

My second attempt was pure perfection (below). As for cutting on a slant like the G2, Bindu's instructions imply that it may be done if you shim the cutting wheel/turret with washers. The idea is to adjust the angle of the cutting wheel to match the slope of the bottle. Not only does it sound tricky, it sounds like another post! Which is why we're going to quit while we're ahead with the Bindu and go on to our next contender.

Don't forget:

CRL Professional Glass Cutter Oil is an ideal lubricant for making clean cuts. 


Ephrem's Bottle Cutter 

Honestly, when I took this little thing out the box, I wasn't terribly impressed. Formed sheet metal and no-wing nuts? Harrumph. Although it DID have 3 cutting wheels, which was nice. Also in the box were a candle, some emory cloth, and a small bottle of sanding compound. (Interesting.) Two of the nylon (or possibly UHMW) guide rollers and shoulder bolts were not attached to the unit. Since there were no assembly instructions, they could have been overlooked before shipment or perhaps they came apart in shipping.

Ephrems (not Ephrams) bottle cutter review

No matter, as it was quite obvious where they went. 


The set up for Ephrem's was pretty easy. It was just a matter of loosening the bracket and adjusting for length. Again, since there was no wing-nut, I needed a pair of pliers and a screw driver to adjust the bracket. (Also note that the adjustment length isn't that long, so there are limitations of which to be aware. But for most applications, it should be fine.) Now, for my first attempt, and, yes, I used one of the G2 fails:

Photo: DIY Maven

Like its predecessors, I got a nice, even cut:

Photo: DIY Maven

And, will wonders never cease, I achieved perfection on the first try with candle/cold water separation as Ephrem's suggested! So why success on the first attempt??  I think it might have to do with the squatty nature of the Ephrem's. The fact that it's made out of compact, formed sheet metal and there are no wing-nuts to make room for, it can sit close to the ground which means it has really good stability. As far as cutting on a slant? The maker offers an adapter on their website for $6 to make such cuts

Photo: DIY Maven

But maybe that first cut was a fluke....

Photo: DIY Maven

Nope. And look at the size of that bottle! (Champagne, anyone?)

Photo: DIY Maven


Then, just for fun, I decided to try to salvage the frappuccino bottle fail from last time using Ephrem's. Again, perfection!

The Creator's Bottle Cutter

Opening its box was a joy. NO assembly! As for my first impressions of the unit itself, it was obvious that a lot of thought had gone into its design and construction. This is what a 100 dollar bottle cutter gets you: injected molded ends with honeycomb for rigidity, 1/4" steel shafting, rubber-coated steel ball bearings, an aluminum backbone with integrated ruler, and very 'grippy' silicone feet. Oh, and a mark on the top of the backstop so you can gauge when your bottle has made a 360 degree rotation. (Very thoughtful.) It also comes with 2 rubber rings, which you'll see later, to direct hot and cold water for hot and cold water separation. 

Creators bottle cutter review

A shot of the integrated ruler:

Photo: DIY Maven

Included is also a nylon (or possibly UHMW) and foam pad to protect your palm. Basically, you're supposed to put the pad, nylon side down, on the bottle, and place your palm on the foam. This makes the bottle slip easily as you hold it in place.  

Photo: DIY Maven

Another thing to note is that the Creator's cutter itself is spring loaded, so it is pushing up on the bottle as you rotate it--you don't push down, more like just hold it in place. This feels a little weird at first, but only after using other bottle cutters. If you're new to bottle cutting, it wouldn't be an issue. 

Photo: DIY Maven

Now let's get down to business. Here is my first attempt:

Photo: DIY Maven

I tried making two different scores at two different lengths on the bottle picture above, but the lines went all wonky. I think it was the nylon pad that did it. Yes, it makes the bottle slip easily as you hold the bottle in place, but it also means the bottle might slip away from the backstop. If that happens, you won't get an even cut. I didn't even attempt a separation with that bottle, so I tried another, this time nixing the nylon pad thing. That score was much better. 

Photo: DIY Maven

Creator's suggest either flame/cold water OR hot/cold water baths. I tried the former and it looked like it separated nicely, but.... 

Photo: DIY Maven


after I cleaned the bottle, it revealed an iffy separation: 

Photo: DIY Maven

For my fourth attempt at scoring I decided to USE the pad again (not pictured) now that I got the slip-factor under control (you have to rotate and keep pressure on the backstop simultaneously):

Photo: DIY Maven

This time I used the hot/cold water method and the two rubber rings that I mentioned earlier to guide the hot/cold water along the score line.

Nice to have:

This replacement cutter wheel for the Creator's Bottle Cutter is good to have just in case. 


The Kinkajou Bottle Cutter

After the folks behind the Kinkajou Bottle Cutter read my roundup, they offered to send out one of their bottle cutters for me to add to the review. I'm going to nut shell it, so here goes...

The unit itself is bigger and heavier than expected (not necessarily a bad thing). It came with sanding paper, a 'glass finishing tool' (to pry off jagged edges left on after separation, which I'd never do, because if you get an even cut, you should never be left with jagged edges), stretchy separation rings, and a bunch of stickers (!)

Kinkajou bottle cutter review

Using the Kinkajou isn't all that difficult, just slip it over a round bottle, adjust the two outside screws to fit it around the bottle, then engage their accompanying levers. To score, engage the cutting wheel lever and spin the bottle until you have a score line around the entire bottle. Sounds easy, right? It is...IF YOU WATCH THE HOW-TO VIDEOS ON THE KINKAJOU WEBSITE. Otherwise, you'll make one wonky cut after another. Even then, you need to finesse this thing. The problem is you can't apply any torque whatsoever with your hands. Doing so will result in a bunch of uneven cuts. Like this one:

Photo: DIY Maven

Once you get the hang of it though, it's fairly easy to get an even score line. 

Photo: DIY Maven

However, if you plan to cut even a slightly square bottle or jar, like the one below, forget about it. The cutter gets hung up on the angles and won't spin. 

Photo: DIY Maven

Hung up on the edges:

Photo: DIY Maven

There are things I do like about the Kinkajou. Its construction allows for easy visibility of the cutting wheel, which is great. I also like the pliability of the separation rings, which are much stretchier and therefore easier to use than those that accompany The Creator's. But.....that's about it, I'm afraid. I just can't get over the torque issue. It's too unpredictable for me. And then there's the whole 'not even slightly square bottle or jar' thing. For more predictable cuts and for versatility in bottle shapes, I'd go for the Ephrem's for a bit less in price. Grade-wise, I'd give the Kinkajou a B, and that's for round bottles only. GRADE UPDATE: Murray commented how the Kinkajou won't score a level line on a slightly slanted bottle either, so for that reason, I'm going to lower my grade to a C. 

The product review unit was provided by Kinkajou. All opinions are mine.  



G2 ($16-$25)

Grade: D

Works but it might be an exercise in futility trying to maintain consistency. Again, the makers say you can cut on a slant, but that proved to be easier said than done. And as for wide-mouth jars? SUPER tricky. Unlike the other cutters in our competition, it does have gravity going for it, which means the bottom of the bottle doesn't creep up like it can on a horizontal bed. For an occasional, straight-forward WINE bottle score, it'll do the job. Although frustrating, it did, eventually, make a nice score. Ultimately, I could see the price making up for the frustration to the user. I'm giving the G2 a wobbly C- for wine bottles only. (And because that part fell off.) For wider-mouth bottles and jars, I'll give it a D, only because there's probably a way to get a successful score if you have a lot of time and patience.  


The Bindu (Originally $50)

Grade: PASS

A respectable, well-made bottle cutter that does the job nicely. Because the makers have disappeared and have, possibly, gone out of business, the cutter will only be found secondhand, which may mean a discount from its original $50 price tag. If so, I'd buy it. As for a grade, I'd give it a B if the company were still in business. Because they're not, it might be best to do the pass/fail route. In this case: PASS.  


Ephrem's ($28-$42)

Grade: A+

Buy Now

A serious contender for both price and performance. Besides those 3 cutting wheels, you get the other thoughtful adders like the emory cloth, sanding compound, and candle. Okay, you can't score a bottle on a slant with it, but they do offer that $6 adder that I mentioned earlier. And, yes, there is a limit to the lengths of cuts, but they also offer a $4.50 extender to deal with that. So, for about 10 more bucks, you'd have everything you could need, assuming the slant adapter works as well as the entire unit does. For the bottle cutter hobbyist, I'm giving this little guy a solid, and surprising, A+. (The + is because of the perfect cuts right out of the box.)


The Creator's (Around $100)

Grade: A

Buy Now

Once you get the hang of it, I feel it will be the most consistent in cutting lengths of all the products in this shootout. The integrated ruler on the back will get precise measurements for your cut lengths, and is a necessity if you plan to cut RINGS. Downsides of the unit are 1. it only comes with one cutting wheel and 2. it doesn't cut on a slant. The wheels are replaceable, of course, but for the slant--there isn't an adder for that. However, Creator's offers a bottle 'neck cutter' for $50 that looks rather enticing. Ultimately, I'd suggest the Creator's for for those of you who intend to start a cottage industry involving bottle-cutting. For a grade, Creator's gets an A.

Thank you so much for this article!! I have the G2 and am ready to move onto greener pastures. I'm going to get the Ephrem cutter. Thank you!

HEATHER on Aug 10, 2017:

i bought an Ephrems and have spent all day with out success. i used the candle and ice cold water as i didnt have ice cubes. no luck, the bottles didnt even seperate. i tried puttong the bottles in the deep freeze to get them cold but no luck. so the trick must be in the ice cube? i also tried the cold water...boiling water baths. no luck!! feeling frustrated

Bev on May 31, 2017:

I want to just cut the bottoms off of wine bottles or smaller sized bottles like a Worcestershire bottle. I want not more than an inch of the bottom. Are any of these cutters capable of that?
Thank you in advance for your reply.

Janice on May 04, 2017:

Thank you for all the detailed information. I have been looking at some of the square bottles (mostly from Bourbon makers) and thinking that those bottles could be very interesting vases or light fixtures. I have never cut a bottle before and will probably purchase your A+grade Ephrem's because of the angle/slope on some of the bottles I like best. Thanks again!!

Nick Jager on Apr 18, 2017:

I've reviewed a few of the same bottle cutters myself and would agree with all the grades that you handed out. Although I thought you were being generous with the 'D' for the g2. It reminded me of when Tommy Boy got excited and claimed that he 'passed!'. Great round-up of all the different bottle cutters available.

Cynthia on Mar 10, 2016:

I am looking to cut crystal decanters. Would Creator's or Ephrem's work on lead crystal?

John Galt on Mar 08, 2016:

Kudos on the head to head match-up. I have Ephram's cutter and love it. It gives consistent and even score lines (both in depth and matching the beginning and ending).

I have been cutting bottles for about two years. While scoring of the bottle is important, proper stressing of the score line is also important.

I used to be very impatient and try to get the bottle cut in two or three passes on the candle. And my success rate was about 50% (terrible).

I eventually realized that successful stressing requires patience. I didn't need to overly heat the score line. I needed to evenly apply small amounts of heat, then cool. But do it over more rounds of heating and cooling.

Now I take my time and do many passes with heating and cooling. While it may take longer, it insures that the stressing is more likely to follow the score line.

Another benefit is that the eventual cut line is very even, and, in my experience, not sharp or dangerous. Because of this, it also requires less sanding.

Once I learned some patience, my success rate has gone to about 99%.

RG on Feb 21, 2016:

Hey! THANKS for this!!! This was exactly the comparison test I was hoping someone had done. Really appreciate it.

Jennifer on Nov 17, 2015:

Murrays bottle cutting technique was great. I went back to review video and the video is private now. I has hoping he'd be willing to repost one that isn't private. I bought the items needed and have done bottles I wanted to try to cut. Thanks!

natasha on Sep 28, 2015:

Hi are you able to review the Luca and C and C, both look simillar, cant decide between those and the Ephram. Got the g2, and as predicted, 1 out of 10 bottles were barely usable, more the amber than green for some reason green seams more brittle. 

Thanks for your reviews, really helpful, although wish i'd seen them after spending 2 hours assembling the g2!!

Andee on Aug 26, 2015:

I`m truly amazed by the C&C Bottle Cutter. Works like a dream.

Yet would be happy to try the other bottle cutters as well :)

Steve on Aug 06, 2015:

Please send me the link for that video on the separation technique you,ve been using.



Murray on Jul 20, 2015:

I don't mean to pull this thread off on a tangent but I thought I would share what I came up with as the best process for cutting glass bottles. It gives me a way to achieve perfect straight cuts with perfect yoeld 100% of the time. It uses no boiling water, no flames, torches, or combustible gases or liquids.  I put together a video and posted the link below. Just one disclaimer:  I used Creator's Bottle Cutter in the video because it has worked best for me in my work. If you are tired of reading about bottle scoring devices you can skip the first 3 mins of the video.

Cheers, Murray

DIY Maven on Jul 20, 2015:

@Kris--I haven't seen a comprehensive review of the Luca yet. If they'd send me one, I'd gladly add my findings to this post. ;) Think they read these comments??

@Els--I'd never heard of the Kent before reading your comment. They certainly DO look alike, but unless I had one in my hands, I couldn't comment on its performance in comparison to Ephram's. As far as manufacture, Ephram's in made in the U.S., Kent is made in China. 

Els on Jul 19, 2015:


Is there any different between the Kent and the Ephrem bottle cutter. On the internet, they look the same?

Carol on Jul 03, 2015:

You can buy anything on ebay!  I think most sellers ship international but be sure to check price.  I was warned not to do beer bottles because it is a different type of glass - because of heat processing.  I just recently tried a few and had 50-50 luck with a clean cut and getting cracks up the bottle.  I was using the G2 and hot water/ice water dipping.  

els on Jul 03, 2015:

Is it possible to cut beer bottles or bottles of 33 cl (I think of the Savanna-bottles, a South African primium cider) with the Ephrem's bottle cutter? 

And can i buy the cutter in Belgium?


Ray on Jun 27, 2015:

Carol. The Creator's Bottle Neck Cutter is your answer.

Carol on Jun 27, 2015:

I have been using the G2 and have done around 200 wine bottles for lanterns.  It is wearing out and I am debating what kind to get now.  I have a friend that wants shot glasses made by cutting beer bottles at the neck.  None of these appear to be friendly to cutting at the narrow section the bottle.  Do you have any suggestions??

Ray Nicholas on Apr 06, 2015:

Good Day DIY Maven. We listen to our customers and we respond. Our separating rings are now more pliable. We went with a lower durometer. (35A). A lot of people try to stretch the ring and then put it on the bottle. That is not so easy. If you roll the rings down the bottle, they go on very easily. Thank you for your in-depth reviews. We always strive to make the best better. Your friend,  Ray Nicholas   President-Creator's Stained Glass
