There are multiple factors going on with a sheath. I understand that many recoil from Kydex, but I'm not quite sure in understand the derision, except if the sheath in question has been poorly made, or doesn't perform properly. A steel/aluminum/copper sheath is just as capable of marring a blade as a Kydex sheath is. Many of us HAVE thought out the design and intention of our sheaths, and to suggest that because we elect to use Kydex somehow proves we somehow lack vision or creativity seems, well... Absurd.
Joey is a martialist, through and through. He KNOWS how to handle himself, and a knife. As much as my knives will perform for someone such as him, he's NOT who I have in mind when creating my knives. I make my kwaiken for Everyman, who with just a little bit of practice can learn to properly carry and employ my knife to hopefully prevent others from entering into harm's way. In a perfect world, NO ONE would need this, and in a slightly less than perfect world, we would all have the training and discipline to properly defend ourselves.
The world I live in is far from either of these worlds.
The sheaths I make for these are lined, however that's only somewhat important to it's non-marring performance. It can also be held open and cleaned out, which NONE of the displayed sheaths can do. The lining serves to make blade drawing and carry ENTIRELY silent, and also aids in retention of the blade. It is also economical. This is crucial, as a quick calculation of what Mr. Hartsfield's version as advertised in 1982 translates into from inflation, by today's standards, is $863, or put another way, MORE THAN DOUBLE what I currently charge for my interpretation of this knife.
If anyone feels so strongly about a sheath that they're willing to pay me double the value of my knife for a sheath, I think we'll find a way to strike a deal, otherwise I'm pretty convinced that my sheath and carry method is perfectly viable.
...in order for me to replicate the 'feel' of RJ's sheath, I merely need to cover it in leather, btw. I still hold mine works as well or better, especially because mine can be cleaned.
I hear my roof calling.
