Neat idea with the pipe. The knife looks nice too! I had one a few years back with beautiful horn covers. Sadly, that was the only redeeming quality of the knife. Yours looks to have a much better fit and finish than mine did. Mine had a terrible action, gaps everywhere, and the edge rested against the backspring when closed. It was kind of sad, because the size and blade shape are a fantastic combination for an edc knife.
I used my knife today to slice up some deer bologna. It also opened up a new vacuum sealer that I used to reseal the half that didn't get sliced.
This stuff is sooooooo good. It is hands down my favorite thing to have the processor make whenever I'm fortunate enough to harvest a deer.
