Wondering if anyone has tried to remove the thumb stud on the hooligan, or if that is even possible. I sharpen on Japanese whetstones, and thumb studs can mess up my stones if I'm not careful. It can also make it tricky to sharpen the heel of the blade. I really like the design of the hooligan, but I am worried that I won't be able to get the thumb stud out for sharpening. Has anyone had this issue? Can We Knives chime in, or maybe someone who has a Hooligan and can give a definitive answer? Thanks.
