Thanks for the positive responses. They are beautiful. I couldn't believe how clean they came out. Of course I'll have to grab another set of handles to install the Stalker blade.
To answer all the questions, I'll do a quick summary:
Bob Lum is the custom maker that produced these two blades. He is responsible for the modern tanto, and is the same maker that Spyderdo based their Folding Tanto, Chinese Folder, and the new Fixed Blade Tanto models on. He is a highly repected maker, having been at the craft for over 25 years, although not well publicized.
Originally Bob and I discussed having him do a blade to replace one of my old PC customs, and that lead to our 10 year discussion with him doing something bali wise. Last August, around my birthday, he finally relented and said he would re-blade a BM 42 I had sitting around. So I sent him the 42 and waited. When he received the bali, he was excited by the project, and one blade turned to three, and he said he would try and complete one of them by Christmas. The third blade, a dagger, is still being worked on. That one should be really sweet, as Bob is considered one of the best grinders today.
Both the Tanto and the Stalker blade fits into a standard issue BM 4x Ti series handle. Which should also mean it would fit into the SS 4x handles. The tanto is amazing in it's ability to fill all the space. It's about as big a blade as you can fit into that set of handles. I'll have to take some pic's of it against the 47 for comparison. The kick is clean, and there is no edge contact with the inner channel wall. Balance is perfect, not tip heavy at all. And the swedge extends up to 1/4" in front of the choil. For those that don't know of the hamagiri (appleseed) grind, it'll be worth your while to go to a Spyderco dealer and take a look at the Folding Tanto. It's a full diamond tip, with exception strength for penetration. The blade is hollow ground out of 1/8" ATS-34 stock. The tang pin is simply peened in place, but fits the existing tang pin cup of the handles.
As for those that would like to be able to obtain your own Lum blades, I'm not sure what Bob has decided to do. This project turned out to be more of a bear than he first anticipated. That tricky "bali simplicity at first glance" curse strikes again. He will make a decision once the dagger blade is complete. For the sake of privacy, he asked me to not divulge any pricing information. Sorry.
I will be sending these to Eric to replace the 2 Jaguar blades I previously sent him, and give these blade the proper handles they deserve.
In case you're not aware, I'm a huge Bob Lum fan; if you haven't done so, you should stop by to see some more of his work here:
