Thanks to Akabu for his instructions earlier in this thread on making a sliding stop for handle lanyard loops. Many thanks for the great tip Akabu.... I owe ya one.
This prevents branches from grabbing hold of a permanent loop hanging off the end of your knife handle and snatching the knife out of the sheath, inevitably at the worst moment as you wiggle your way through tangled brush.
Below is a composite picture of my construction of the Akabu Loop.
1. The components -- an Okuden Sharp Thing II knife, length of 550 paracord, and a 3/16" inside diameter neoprene washer. Note that the knife came from Brian with a full coating of Kalguard, but I've removed it from the bevel grind while running various sharpening and patina tests on the knife.
2. Rather than using the Lark's Head Hitch (aka Cow Hitch) shown in the machete pictured above to "fix" the lanyard to the handle, I simply took an extra turn through the lanyard hole at the end of the tang.
3. Rubber washer slid over the two ends of the paracord.
4. Overhand knots tied in the ends of the paracord to keep the rubber washer from sliding off in use.
5. "In use" configuration with the rubber washer slid to the ends of the paracord forming a loop for wrapping around your hand.
6. "In use" configuration with the rubber washer slid against the tang of the knife for sheath carry to avoid snagging on branches.
And here's a picture with its kydex pants on, ready for the trail.
