hello - i was wondering if it is possible for me to take the thumbstud off of a 484 bucklite?- the handle is to small for me to use the thumbstud safely - when i push up on the stud the handle is to small to hold on to , making all my fingers slide across where the blade goes into the handle and because this is a lockback, if my thumb slips off the stud it will close on my fingers- i know this but i also don't want this to happen in case someone else is using my knife- is there a way to do this with basic tools or is this something that would need to be done in a shop of sorts?- can it be unscrewed? or is it solid?- if anyone knows please help....
