It has been my experience with cutting glass for the stained glass craft that no two people are alike when it comes to glass cutter preferences. I have taught classes as well as learned the craft myself and there are numerous factors to consider.  First I will say that I personally prefer the age old,  plain manual wheel type cutter with no frills. When I learned to cut glass there were no oil fed cutters and so I learned to keep a jar with oil on a cloth with my cutter always in it. I have a preference for style and even brand.  I prefer a ball head cutter by Fletcher-Terry. Now that being said, I am sure there are many fine brands out there but this is the one I like best. You however may find a whole different style and brand that you like. My requirements are that they last long, cut consistently and feel "right" in my hand. The ball end is great for tapping your score when you have a particularly tight curve. Many of the oil fed cutters have the ball end as well, but the cutter itself tends to be heavier and the swing of the ball end is not as comfortable for me. The plastic oil fed cutters are lighter in weight for those who get tired out easily.

I always suggest for beginners that when you are learning to cut glass you should try out as many different cutters as you can get your hands on because at some point you will find one that "feels" better in your hand. That is the one you want to use.  A lot has to do with the size and relative strength of your hands. One of the reasons I prefer a standard cutter is that the oil fed cutters are wider and do not fit between my fingers comfortably. I also wear leather gloves when I cut glass. They not only protect my hands from numerous cuts but from blisters and sore hands and fingers. The best gloves for this are nice soft thin leather or even suede.  So if you are going through the pains of learning to cut glass you might as well learn while wearing gloves for comfort and safety sake. You will thank me for this one day. Trust me when I say that you will get better at cutting the glass with lots and lots of practice. Just keep trying and keep cutting, it gets easier.

Another nice cutter that many people find relieves some of the pressure on their hands is the "pistol grip" oil fed.  This can make cutting those tight curves easier as well.  This is probably the most comfortable grip for a lot of people.

If you are cutting a lot of straight cuts by all means use a strip cutter. Not only will they save you on replacement cutting heads because the pressure exerted while using one is generally more consistent so the cutter head just last longer but they will save you time and frustration. Don't tap a straight cut, learn to use your running pliers if you cannot snap the glass on the edge of your table. Tapping a straight cut will just give you little round snags in your break.

Lastly, I will recommend that you use the "best" tools you can afford. If you are going to be doing this for any time at all you will find that they are worth the few extra dollars saved by having them last longer and work better. Take care of them, keep them clean and oiled and they will serve you well.
