We tried to make a sharp knife edge out of a piece of obsidian. We even tested the sharpness using our Industrial Edge Tester. We were pleasantly surprised by the results. View the results of our sharpness test.

I had a wonderful experience with your salesperson. He treated me with courtesy, showed care about my needs, and taught in a polite manner. His patience is commendable and his knowledge is a real asset. Thank you much!
