My brother Steve is a talented metalsmith, and made me this knife for Christmas. Then he wrote me this e-mail describing its construction:
"the knife is handmade out of O-1 tool steel. Hand-forged from a rectangular steel billet It's a high carbon steel that will naturally rust/oxidize - no sweat. This is normal and expected with hand forged knives. Rub it with a scrubby pad to knock the surface rust off and dry off after using it and the natural patina will end up being a dull gray/black. Again, normal. Old-timey knives before stainless steel all do this. You can sharpen it easily with a kitchen sharpener or stone, or dad's belt sander like he does and that works best. The handle is a linen/epoxy sandwich called marcita and held on with a clear epoxy and brass handmade rivets. All the knives I made this year were forged in my crucible forge and on Dad's anvil he had from years ago. I'll keep making them."
How badass is that. Plus the duct tape / glove finger sheath.
