Pick Your Glass Cutter

The most important part of this entire job is the glass cutter. It can either make or break your entire task. That is why it is so important that you are able to get one that is good enough to cut through the glass that you will be cutting. Remember that this is not just any type of glass. This means that you will not need just any type of glass cutters. You will need to shop around and make sure that you have one that is going to be able to do the job right. Do your homework and look into each one. Make sure that the ones that you are looking at specializing in this specific type of duty.


The best way that you will be able to prepare your glass is by picking the right lubricant. There are several different types of cutting oil and actually, most different types of lubricants will work. Even a 3-in-1 oil will do the trick. Just be sure that it is something that you feel comfortable getting on your hands as this is something that is likely to happen.


Once you have prepared and have the proper tools, you will need to begin by scoring the glass. Basically, what this means is that you will need to create a type of scratch where you want the glass to part. In order to do this correctly, you will need to hold the glass cutter as if you are about to stab the glass. You will need to have steady hands to do this. The more vertical and steady you are, the easier the glass will end up breaking for you.

The best way to stay accurate is to guide the head of the cutter with the thumb of your other hand. This will help you to get not 1, but 2, steady hands and will help you to more accurately guide the cutter itself.

Part the Glass

There are multiple ways that you will be able to separate the glass once it has been scored in a straight line. The most popular and what is most often thought of as the easiest way is to hold your glass on both sides of the score with both of your fists. With both thumbs above the glass and your fists below it, hold on to the glass as firmly as you can and rock both hands apart.
