This green glass-bladed knife was made using the old ways, using the technique of knapping, which was used by our stone-age ancestors to shape stones into tools. It looks good, the only thing is that I don’t know how I would use it. I mean, I am totally down for some fiber-optic glass steak knives – but a fighting knife, I haven’t had a knife fight since I can remember.

This is what I call my Fighting Knife design. The emerald green fiber optic blade makes this knife a rather striking display piece. I enjoy picking it up, feeling it weld to my hand and watching the blade shimmer and dance in the light.
