Rex,

Thanks. I know RMK stopped putting sawteeth on the model 5 grinds at some point, not sure when. Curious if ALL of the Aircrew Survival's were made with a model 5 grind, or if some are the combat companion grind.

The one on ebay appears to be a combat companion with sawteeth, paired with an older JRB. To me, the knife with custom spacers mated to a JRB do not match up. Anyone, feel free to correct me if I'm wrong -- I will gladly stand corrected.
