This question has come up several times since the BK-10's have been shipping out.
I posted a quick tutorial in the middle of another thread, but I thought I'd give the topic its own thread for ease of search.
Here's a quick mod that helped my BK-7 better fit its sheath:
1. Remove the liner from the nylon sheath, and dip the end in question into some boiling water. Hold it in for about 30 seconds. BE SURE you have some Krispy Kreme donuts handy.
2. As soon as you take it out of the water, shove in the knife. I wrap my blades with tape when I do these mods. The liner will shrink just a touch as it cools, so it helps for a better fit if there's a little extra between the liner and the knife. Otherwise, the fit is generally too tight.
3. The result is a sheath liner fit to the contour of the thumb ramp and a better fit all around.
Easy peasy, as my son would say.
