What Customers Are Saying

The Kobalt glass cutter is a mixed performer. Many users found it effective for basic glass cutting tasks, praising its comfortable handle, smooth roller, and ability to make clean, precise cuts. However, some reported issues with thicker glass, insufficient scoring, and undesirable glass breakage. Proper use and maintenance, such as oiling the cutter, appears important for optimal results. The cutter may not be suitable for more demanding applications or thicker glass.

Unless you’re very strong the tool is ineffective.

Awkward with too small a cutting wheel.

Would Not Recommend

I bought the glass cutter to cut a mirror. The design of the cutter was awkward to hold and if it wasn’t held at the correct angle all the length of the mirror it didn’t score the glass. The cutting wheel was so small it was difficult to see if I was cutting exactly where I wanted to be cutting. The mirror did not snap properly and was destroyed. I intend to return it for a refund. Unfortunately the cost of the mirror is a greater loss.

Great cutter

[This review was collected as part of a promotion.] This glass cutter was perfect for my glass I needed to cut to make my crafts for my church. It cut perfectly with such precision and no cracks.. I will be using this moving forward for all my glass cutting needs.

Good for thin glass

[This review was collected as part of a promotion.] So far, the Kobalt 6-in Glass Cutter has been super helpful cutting through thin sheets of glass. I haven't found it to be as easier with thicker glass, but that I could be because I haven't practiced enough. Applying the right amount of pressure was no problem with the think glass, but the thicker glass is proving to be trickier and my edges aren't as clean.

Overall Good Cutter

[This review was collected as part of a promotion.] This cutter is a reliable choice for basic glass cutting, especially with thinner projects. Its comfortable grip helps you maintain control for precise cuts. Keep in mind, it usually needs firm pressure and a few scoring passes, so it might not be the best fit for very detailed or complex cutting tasks. However, it performs really well when working with thinner glass, making it a helpful tool for many glass and ceramic creative projects.

Great product

Would Recommend

[This review was collected as part of a promotion.] It works great and was awesome for cutting small glass pieces for a craft project I did with homeschool students. It does sometimes leave a bit of an edge on it so be prepared with some low grit sandpaper to get any off. Otherwise great.

Glass Cutter

[This review was collected as part of a promotion.] This is the first time I used a portable glass cutter. It was compact in size, being easy to store. It has handle that helps with control and easy movement. It was not very sharp and took some effort

Handy cutter.

Would Recommend

[This review was collected as part of a promotion.] I bought this to cut a piece of glass I have sitting around. I need to cut the glass to the length of my bird cage. With a little bit of cutting oil and applying some pressure, it’s easy to score the glass. The ergonomic handle fits nicely in my hand.

Great small glass cutter

Would Recommend

[This review was collected as part of a promotion.] I used this to cut glass for a stained glass project and worked great for my project. The handle was very easy to handle and cut very well. Using the product with a little bit of oil makes a huge difference.

Great for classroom projects

Would Recommend

[This review was collected as part of a promotion.] As a teacher, I appreciate how easy the Kobalt 6" glass cutter is to use. The grip is comfortable, and it scores clean, straight lines, perfect for simple stained glass or mosaic projects with students. Just keep in mind it’s best for straight cuts, not curves.

6 inch glass cutter

Would Recommend

[This review was collected as part of a promotion.] This is a handy sized glass cutter. The handle has a nice grip and the cutter is very sharp. It is great to use on not only glass but other objects that are about the same hardness as glass, I would think.

Pretty good!

Would Recommend

[This review was collected as part of a promotion.] This tool is great for very basic glass cutting projects. It has to be very thin glass. I’ve found it won’t work on thick glass. It is nice to hold and easy to control. It’s great for stained glass projects!

Kobalt Glass Cutter

Would Recommend

[This review was collected as part of a promotion.] Kobalt glass cutter, cuts glass up to 1/4 in thick. Awesome handle that fits perfectly into your hand. Which helps to have the best control.

Innovative design

Would Recommend

[This review was collected as part of a promotion.] This is a great tool. A new modern twist on an almost unchanged design since its inception. The comfortable handle feels good in the hand. The finger hole and thumb ridges give you complete control while cutting. This tool certainly lives up to the Kobalt name.

Nice Glass Cutter

[This review was collected as part of a promotion.] Nice Glass Cutter! It’s light weight and small which is good for my hands. The design is very effective for cutting precise cuts. It cuts glass up to 1/4 inch thick. The heavy duty tungsten carbide cutting wheel makes the cuts easy.

Handy Sharpener

Would Recommend

[This review was collected as part of a promotion.] This straight edge sharpener is very handy to have at home. It's different than the whetstones I remember my dad using with oil. This requires no lubricant or you can use it with a bit of plain water.
