I have 3 Buck model 313 Muskrats; one is my EDC, one with great handle scales and snap but with worn down blades, and another that I just recently won that has terrific, almost untouched blades but with horribly disfigured handle scales. My question is: will Buck remove the old blades from one and replace them with the ones that are in great shape? And if not, is there any way to possibly swap out the handle scales? Thanks.
