Headhunters Knot...

I tied this 'Headhunters Knot' with a length of gutted paracord, just making a single pass around the center section of an AA Tactical Maratac Flashlight. I'd much rather of used some nice leather for this knot, but did not have any on hand. Variations of this knot have some interesting looking patterns.

A couple more headhunter knots shown tied with red 1.4mm cord over wooden beads, for use with paracord wrist lanyards.  One is doubled and the other tripled.

The number of 'passes' can get confusing with knot terminology and can mean different things with certain types of knots.
