Commissioned by a bud to make this knife, close to his design and I modified it a bit to work better (he's never designed a knife before, so was happy with the additions I put in it):
He wanted me to rough shape the Micarta handle scales to the shape of the tang, but wanted to finish shaping the handle itself, so making a form fitting sheath became difficult since I didn't have a means to mold the sheath around the 'non-existant' handle until after he was done. So I came up with this lacing set up so he can adjust the friction as he liked, and I wouldn't have to work on the sheath after. Nice little toggle made from deer antler as a decorative peice and lace holder. O1 blade has been sandblasted then soaked in hot white vinegar to oxidize it to make it pretty rustproof (for a high carbon steel, this is way cool!)
And yes, that is a bottle opener at the rear of the grip.
