I recently got a GEC EZ Open Jack EDC, and the bone isn't fit 100% perfectly. There's no gap between the bone and the bolster, but the liners and the bone aren't flush, and there is a bit of a rough edge where the liner sticks out a minute distance from the bone. What can I do to get rid of this? Should I just take some 1200 grit sandpaper all around the edges of the knife?
