So, the BK-4/15/16/17 are due out soon. This means I need to start squirreling away a bit of cash here and there in order to place an order as soon as they become available. One stop shopping is the only way to go....gotta be the first kid on my block with the whole set. Like most people here, I suffer from a disease that makes me invest in knives (along with firearms and other tactical and "tacti-cool" stuff). When treated correctly, and cared for, they will last a lifetime. I already see the 4 replacing my HI kukri, and the 15 replacing my SOF Seal Pup on my FLC. What am I going to do with the 16 and 17..........still not sure. They will see use here and there. I like to break out my collection and use a few that havent seen the light of day in a while.
