Anyone know where I might find an original flap style sheath for one? I picked up a 116 off Ebay, sans the sheath, and would like to make it whole again. I'm not familiar with any of the knife trading sites.

I have had to find sheaths for older Buck knives before and always only ever found then right there on ebay. I have spent some time looking at other places, but have never had any luck...I have had to lurk on ebay for a while to get a nice one, but eventually one came up for sale. Good luck.
