Hello all.I recently purchased a Buck Taclite.I really like the style,blade shape,size,etc.The only thing I dislike are the type of thumb studs on this model.They have a very rough checker pattern that I find will wear a hole in my pocket every time(even after a little sanding).My question is this: can these be removed without too much difficulty?And if so,where can I get replacements that are not so rough?Thank you for any suggestions or comments.
