How to Use a Glass Cutter.
—“There are tricks in all trades but ours,” said the carpenter as he drove in a screw with a hammer, and so if you will dip the steel wheel cutter into some kerosene before each cut is made you will be surprised to find how easily it cuts.
To use a diamond cutter, hold it just as you would hold a pencil and grip the three sided part with your thumb, index and middle fingers, as shown at [C]. Then place the cutter against the straight edge of your T square, press it down firmly on the glass and draw it along evenly.
To make the right kind of a cut hold the diamond at a sharp angle, that is, very slanting, and raise it slowly until a smooth, sound and clear cut is made. Don’t hold it straight up and down or you will surely spoil it, and never never cut twice over the same line.

It takes more skill to use a diamond cutter the right way than to use a steel cutter, but a little practice will make you proficient.
