Hello all! Im new to Blade forums, but not necessarily new to knives. I EDC a esee 3 at all times when not at home, and I love it. I recently picked up an old cattaraugus 225Q. I originally thought to just put it up as part of a WW2 knife collection Im starting. but...man, I have to say that holding that big chunk of 1095 in the hand just begs you to use it. Here is my quandary; The knife was bought very cheap off of craigslist from someone who had no idea what it was and didnt really care. It came with the original sheath, and it is in ok shape, with the only real damage being the reciever side of the snap strap being missing completely. After close inspection I actually found just what you love to see on these old sheaths...a name and serial number on the back of the sheath. Its VERY faint, it wont even show in pictures. However I can definitely see the last name King, with the first name being Chris or possibly Curtis. Under that are the numbers, I cant make them all out definitely yet, but there are definitely at least 8 numbers. The knife condition itself is pretty good, has the barest amount surface rust at the base of the blade, with the rest having the old knfe patina. Its dull, has scratches from being used as a crowbar, but gives great character to it. The leather washer handle is all there, and good and tight. The pommel is completely intact and in good shape. Only thing loose on the whole knife is the cross guard is a tiny bit rattly. I just dont know what to do with this knife. What is an acceptable amount of restoration if I decide to just keep it as a collector/conversation piece? Can I remove the small amount of surface rust and sharpen it without ruining any collector value? If so, whats the best way to do this and maintain the patina? If I decide to use it Ill just5 go full bore and polish it all up right. The handle I wont change at all, it fills my hand perfectly. Anyway, sorry for the novella here, and Ill try to get some pics up tomorrow. Thanks for any and all suggestions.
