Neck knife suspension

There is a problem I still need to solve about neck carry.

When carrying a neck life, there is always a risk to fall and have the shealth lace catch a branch or some other obstacle, which would result in having yourself hung by your own neckknife lace. Not very likely but still plausible and very stupid risk.

The most obvious (if not unique) solution is to use a fusible lace which means a lace that will break or undo itself before you get any serious damage. For that purpose you need a lace that won't take to much stress, but on the other hand a too weak lace may undo itself too often in a everyday use.

One has to note that the hunging yourself is more about spine damages than suffocation, contrary to what you see in many western movies, death occurs rather by brutal spine rupture rather than slow suffocation, which means choosing a string with tension strength below your weight is not enough and I have no idea how much a neck could take in terms of brutal deceleration.

Most companies solve the problem by selling knives using "plumber chain" as necklace, those are calculated to break before you take any damage, but those items are still pretty specialized and some dislike their appearance.

I for myself make those suspension on the spot from avaible material, and so far have disregarded the problem although I know I should look for a solution.

I've vaguely heard about some knots that could do the trick, but I fear those to be either too loose for practical use, and not releasing quick enough for safety. I've been thinking of getting knots behind slightly too small holes on the shealth, so in case of emergency, the knot might go all the way through, or fusible shealth. Also been thinking of tearable shealth suspension.

So what is your experience with that problem? Any idea? any secret setup? any cunning trick?
 
I carry mine under my shirt. I cannot, in reality, foresee it snagging on a branch and hanging me. If I take a fall in the woods, that's one of my last concerns. YMMV.
 
When I was in the Marine Corps several people brought this issue up about the dog tags. The issued (plumbers chain) was not robust enough for the most part and 550 cord ran the risk of hanging death. The solution that seemed to work was to take 550 cord and remove the inner strands, then run the "plumbers chain" through the outer shell of 550 cord. This is the important part of why it worked though, the 550 cord had to be about 1" shorter than the chain. Then the ends of the 550 cord were melted onto the chain and only a little bit of chain was left showing ( the area where the chain latched).

I don't really know why it worked but experience proves this method to make the chain strong enough to last while still having enough chain un reinforced so that if caught it would break.

Hope this Helps

If you use paracord you can use... well idk what to call them. Come kind of clip? the ones you can find on things like hoodie strings. you compress the spring and it makes a hole you can put the ends of a cord through, and if pulled on it will just slide off the end of the cord. Sorry for being so vague.
 
I run ball chain through some gutted paracord leaving the clasp uncovered. Then I tuck it under my shirt normally.
 
I've had good experience with simply melting the two cut/lightly frayed ends of 550 cord together, forming a "fused" area like what you mention. In my testing, it'll take some pulling to be sure but would not support weight over approx. 25lbs.

I guess it also depends on how fancy you get with the fused ends. I simply light both ends with a lighter or candle until both are actually on fire as it were, then quickly put the two ends together, blowing on it to cool it, and then using my calloused guitar fingers to minimize the girth of the fused area as it cools. YMMV, but works great for me. Beyond that, I definitely wear anything suspended by 500 cord under one layer at minimum.

+1, this is pretty much how I do all my neck cords and have for years.

Never had one break just from pulling the knife out, but I can break it if enough weight is put on it.
 
you could disect one of those cat collars that are designed to stay on, but designed to snap off when they are under some tension.
 
in the military we had break aways for stuff around our necks while working the flight line, let me see what I can dig up.

here's just one example of what I'm talking about, simply type in break away lanyards.

Chances are if you live near an airport or a military base they've got them in stock.

With a Kydex sheath you can set the retention as tight or as loose as you want with a proper retention screw/post... I use paracord with a section of ball chain that will break away in a snag, but its still very secure in normal use.
 
I use the gutted paracord over the chain and then use some shrink tubing to hide and/or bond the frayed edges of the paracord...it works so far...

only problem with them is that you really need one a couple of sizes too big, or heat sealed ends of cord can jam, as they won't feed through the mechanism properly.

my method is to have a short "breakaway" section in the cord, made of a short length of monofiliment fishing line tied between the ends of the cord, covered with a lenght of heat shrink tubing (for comfort).
you could also use small loops of fishing line to link the ends of the cord to the holes in the sheath.
 
Has anybody actually had first hand experience with "hanging" from your neck knife??

I have carried a neck knife exposed since 1994 and have never had it even snag on anything. That is in a warehouse, bush, farm...., and with ball and chain, paracord, other cords etc. I worry about that eventuality as much as I worry about zombies, meteors, or Scientologists.

My thoughts, exactly. Seems pretty far-fetched, to me.
 
I made a breakaway connector...

You thread a cheap plastic bead onto each end.
Then you double the cord over and thread it backward through the other bead. Repeat for the other side.


Then you tighten it up so the beads are touching.

Under heavy strain, if it doesnt slip out, the cheap plastic beads will actually break, releasing the cord.

Make sure you melt the cord ends, some of the nessasary friction comes from that.

And of course I can't guarantee a specific breaking strenght, YMMV, use at your own risk, do testing to your own satifaction etc.
 
Back in high school days the shop apron straps were lightly sewn. We were warned not to sew them better as they were designed to be break away when caught in a machine. Good idea . Good shop safety includes NO jewelry ! There is a long list of accidents including death, dismemberment etc from that !
There have been many cases of children injured when clothing such as hood cords get caught .Of course kid's styles with baggy clothing invites accidents !!!
 
I use a cord-lock for adjustment ( on paracord). About the snag/choke potential, I can pull the blade ( Becker Necker) and cut, or in extreme, the cordlock would slip. I only burnt the ends, not knotted them. The adjustment factor I really like alot, instead of a given opening.
 
Does anyone remember Pop Beads? They were meant for kids, but a couple of years ago I saw what amounted to an industrial version that was touted as "safety chain." I can't remember where I saw them: has anyone else seen them?
 
Does it have to go around your neck? A good way to carry a neck knife is under your weak arm. Take about 6' of cord and thread you knife though to the middle. Tie the ends together using a double fisherman's knot. Then make a figure 8 with the big hoop you now have. Turn one side of the 8 over again in the same direction. Now put one arm through each loop as if you are putting on a shirt. It should fit like a shoulder holster and it is adjustable via the fisherman's knot. It is also very inconspicuous if you are wearing a vest, shirt, jacket or back pack.
