I myself seldom use a pocket hone to sharpen the knife..much easier and safer with a larger stone. But it is great to have in case of emergency sharpening needs...and just looks so darn cool! lol
I often get requests for the pocket to fit fire steels or even Gerber multi-tools but the sheath has to be big enough to handle a large pouch for something like the 600 multi-tool. Just finished a monster sheath with multi-tool pouch for a Randall model 12-9..guy runs a survival school up in Michigan.

They say your memory is the second thing to go...I forget what the first thing is.
