I suspect this question has been asked before but I would like to seek advice as to what is good or acceptable practice for the care and preservation of a HJ Knife. Obviously certain things are definite don'ts i.e. using wire wool or abrasives and personally I would not consider sharpening either. On the other hand, I would imagine a light coating of oil (3 in 1?) would be good to protect the blade. But what about cleaning, polishing or buffing? I have seen references to all of these on various sites. Also, what could or should be done to prevent deterioration of the leather work? All suggestions or advice would be much appreciated! Thanks, Nick
