Those who keep an eye out for neck knives, I'd like to go further and ask what neck knives stand out in your mind as excellent examples, and what do they excel at, and what could they do better? Also what are examples that are marketed as neck knives that might seem good on the surface, but absolutely fail in practice, and why?
Those that fail, in my experience, are not so much because of the knife but because of the sheath. And there are a lot who fail, and by fail I mean the knife loses almost all retention in the sheath after a few months of use... Very disappointing, especially if the knife is great in all other regards. You can still use it as pocket carry, belt carry or pack carry but it failed at being a necker.
As a start : IMO, the real neck carry is handle down, hence my fetish with safe retention (this said, you can neck carry almost any knife handle up. Pulling the knife is not so natural and easy but it works).
Let's focus on "handle down", the most efficient neck carry.
In leather sheath : the tightest fit will still need a strap of some sort to secure the knife. Leather gets supple over time, retention will diminish and sooner or later the knife will fall out. I have no problem with a press button strap, it works. Thing is, you need two actions to draw the knife. Less natural and easy...
In Kydex sheath : thanks Scagel, there is Kydex. Yes, but actually no... The best working sheathes are made of Kydex or FRN but some of the baddest, too !
As a general rule :
- When the retention of the knife in the sheath relies on the blade's heel or a nub at the blade's heel (be it with sharp or more or less rounded edges), the steel will eat the synthetic away and the knife, sooner or later, will fall out. Not good. There is a long list of brands who chose that solution, even on pricier knives.
- When the sheath snaps onto the handle, that works very well and for a long time : synthetic on synthetic is a secure match that is bound to last. However, it impacts the handle design (at the bolster/guard mainly) and the handle can show scuffs in that area.
I can show a few knives where the "neck carry handle down" design was aptly nailed. I have been carrying some of them for years now (and my gut still feels safe).
From top to bottom : Cold Steel Secret Edge and A.G Russell Woodswalker. The three down are nice knives but failed at handle down neck carry.
Another A.G. Russell (Sting 3B). Works perfectly and will do so for very long (two lateral claws snap into the hole in the handle) :
A perfectly made necker/sheath unit (Stoil Manchev, on BF's Knife Maker Market). Easy to draw and totally safe retention :
Another one by Stoil Manchev. Very strong retention. I could hand it down to the next generation, they don't need to fear for their gut !
