Have owned a bamboo kwaiken from James since 1992. Got the shoulder harness and jsp static cord sheath for it at that time.
Also recently purchased the v-gar system and wear it everyday now.
James makes all the knives, I'm not sure who does the sheaths but I suspect it is James as well.
That kwaiken is the knife people gravitate to when shown samples of the collection I have amassed over the years. Most think it is the best knife I own even over the Bagwell Hells Belle or Ed Fowler knife with Rambouliet sheep horn handle.
I carry the shoulder rig often enough and hardly ever use the static cord setup as I carry two defensive folders and a firearm as well so there isn't room for the static cord tucked into the waistband of the pants as a rule.
Ocassionally I'll leave one of the EDC defensive folders home in lieu of the kwaiken in the static cord sheath but I really like the shoulder rig.
When I first met James he would not make his shoulder harness for anything but his own products, however that has changed over the years and I will be getting a custom rig made for the Belle as well before the years out.
His products are some of the best offered in the market and his sheathing systems are the ultimate for concealed carry in my opinion.
You can't go wrong with anything James puts his hands to from what I've seen and heard others testify to over the years.
BTW--James was using A-2 steel exclusively at the time I hooked up with the kwaiken. I think that is still the case. It was the first A-2 knife I owned and I have to say, the more I use that knife the more I like A-2 steel in my blades, trouble is, not many knives are made with it so the choices are slim out there. The kwaiken takes and holds an edge that is "scary sharp".
