A few folks have shown interest in chipping edges, and since I have done quite a few miles of it, here's my take. Chipping glass is not rocket science. Some of the first tools were made by "knapping" flint and other hard materials to leave a sharp edge, and what we do today comes from that knowledge. It is simply the controlled breaking of the edge to get the effect you desire. There is no way to get around the facts --experience comes with practice. I have tried to make a pictorial that may give you an idea how it works. See what you think!

First, photos of a storebought chipper, and one that I made for chipping 3/4" and 1" heavy plate.

It is important to pay attention to safety, particularly your eyes. ALWAYS wear eye protection when chipping, and here are a few other good ideas. Gloves, apron, long pants, closed shoes and a large rubber clown nose.

This edge is best for furnishings where there are kids, or general public.

This is the best looking edge, but should not be used on furnishings where there are children, or much traffic. High collision danger.

These photos are of an industrial wetsander, but the principal is the same. Remove the sharp spots.
