Okay, you guys got me inspired, so here are my adaptations to the Becker Necker.
I liked the wrap that SkunkWerX did, but I wanted to try it with smaller diameter stuff. I had some braided 2mm line that is fairly stiff and I htought it would make a good handle wrap. I tried wrapping all the way around and it worked okay, but is just wasn't as sexy as showing off the skeleton holes in the knife handle. I think Skunkwerk's approach feels better too and the holes inprove traction on the grip. I used the same basic approach that SkunkWerX did, but using the smaller line for a lanyard looked a little weenie, so I terminated the wrap in clove hitches at each of the end lashing holes and melted the ends into the rest.
I made a lanyard from Nite Line that is reflective and glows in the dark and mated it to the knife with a simple lark's head knot and then made an overhand knot to finish it off. Not snag free, but simple. The idea of using a toggle with a compass in it was really good. I had a Brunton compass that was made to go on a watch band and I've been looking for a place to put it to good use. It works fine on the lanyard with an overhand knot on each side. With the lark's head knot, the lanyard and compass can be removed form the knife without a wrestling match.
I really liked the idea of cutting some thumb grooves in the top edge and went at it with some small files and finished up with a small hard Arkansas stone. I borrowed a little clear fingernail polish top coat from my daughter to coat the bared steel. There are six grooves in 1/2".
I used a small Tek-Lok mounted with the release tabs upwards and two screws through the rivets on the blade side. The holes just barely line up, but it is possible to get it mounted without any adapting. I did use the thick rubber washers in cloded with the Tek-Lok to even up the mount (note the red arrows in the photo). This mount tends to let the knife handle hit my love handles with the knife on my pants belt, but it is perfect on the compression strap on my day pack and slides back out of the way on the waist belt of my larger pack (GoLite Jam).
I saw a survival setup somewhere on the Web where someone cleverly took a wire saw and ran it through some plastic tubing and then used that as a neck lanyard for a small knife, whistle, firestick, compass and micro LED light. The smaller items were carried on a small length of line that joined the two ends of the wire saw and formed a break-away if the rig got caught in something that might throttle the wearer. I'm of a mind to join the wire saw ends with some dogtag chain and try carrying the knife and essentials that way too.
After posting this, I cut some inner tube rubber bands to put on the sheath. The tube I was using was a skinny one and I wondered if it would make a handle for the Necker. I tried it and it was so-so, and as I was pulling it off, the knife popped out of the sheath and I just got back from the ER (after EIGHT HOURS), with four stiches in my middle finger. Be careful kids!
