Just curious if anyone has removed the Rifts thumbstud. They do not have a torx in them. They just have slots on the outside exterior side of the thumbstuds. If there some tool that fits over the thumbstuds into these slots? I don't want to take pliars too it and scratch it to pieces. The thumbstuds stick way far out and I can not sharpen the knife properly with my belt sander. The other benchmades takes 2 #6 torx to unscrew the thumbstuds to sharpen them properly, but the rift is way different.
