I recently received and Buck 500 that belonged to my Grandfather. It is the only thing I have that was his and it is in shotty condition. The blade will not lock in and it has obviously been used in its life so to speak lol. My question is.. If I send this to Buck to get it repaired so I can actually use the knife then pass it on to my kids later in life will they fix it or send me a updated knife? This may be a very stpid question but I have never sent a knife in for repair before. Thank you all in advance for any information.
