I came up with this sheath for my Wolf Creek Altoid knife. I couldn't see putting such a cool little blade in a dark box and not looking at it until an emergency, so I figured it would make an outstanding neck knife......... and it does
It's three layers thick, with a thicker layer in the center that is the same thickness as the knife. Saddle stitched and waterproofed. The lanyard on the blade is long enough so that when I insert my pinky, it pulls everything nice and tight. I may add some jimping on the spine yet...
To hold it all in, I used two leather thongs and a really tight fitting oval Antler bead that Highlander was wonderful enough to send me for another project in the works. Pulling the bead to the sheath snugs it up, pulling down just a half inch lets the knife slide out. The oval gives me good purchase, but doesn't sit any wider than the sheath 550 cord in double slip knots for the neck lanyard so I can resize based on clothing, or have a longer cord for emergency use. Here's a pic:
Thanks for looking!
