Tom,
Right now the first 500 SB3 blades are winding their way through our metal shoppe, which means (if all goes according to plan) they should be in our shipping room probably around october.
These are BG-42 and will be serialized. The sheaths are cordura with kydex liners - way cool. I strapped one of those things on and felt just like a Force Recon Marine (usually I'm a Force Recon coward).
