well, it sure is possible, but with that knife, it may be a bit harder.
if you see no screws or anything anywhere, that's most likely because it has 'hidden pins', which means the pins are polished so much that they 'go in one' with the handle. so if i were you, i'd rather get a knife with real torx screws, and unscrew that one instead.
by the way, where would you get a comb which will fit?
