Well, I'll tell you what I know.
I spoke to Will F. of Camillus, and getting all the "Wee Penn" knives we want is no problem. Getting the 'Chai' etched on them is no problem either except that the work would have to be farmed out, with probably 100 as a minimum order. The other problem is that someone has to take the time to put all this together. I can't speak for MikeT and Spark, but they may not want to take this on right now and commit to knives that may or may not sell.
Judging from the response to this thread this may be an idea whos time has past. As for me it would have been nice to have this knife as a way to remember James, but I don't think this is going to happen. As an alternative what I did was to buy a handmade mini puukko from Swedish maker Maihkel Eklund, which I wear around my neck every day. I can't fail to think of James when I see it.
No matter what happens anyone who came into contact with James won't forget this wonderful man.
That's all I know.
