Question:

Could someone create a Diamond edge sword, and if so, How effective would it be?

I once heard that it was possible to create a sword with a diamond edge that was laser sharpened and was incredibly powerful compared to regular swords of fine craftsmanship. I'm wondering if it's really possible and how good it would be.

Best Answer - Chosen by Asker:

The sword edge would have to be lined with diamonds. So you wouldn't have a continuous edge, but more like a hack saw blade.

Diamonds are hard but relatively brittle. Strikiing something with it would result in breakage of the sharpened edges. It would work well as a cutting edge.

Diamonds are used in abrasive applications, like industrial "sand" paper and grinding wheels. But the quick loss of a sharp edge would make for a very dull blade.
