My only issue with the Natchez, or most modern interpretations, is the lack of a sharpened clip. Same with the SOG S1. It is my understanding that the knife use in the Sandbar Duel was a large butcher knife with a sharpened clip ground into the blade. Rezin Bowie commissioned many different styles of genuine Bowie knives, from several different makers, evolving the design. But, all of the examples I have seen have had a sharpened back edge, whether a clip or a swedge, such as the knives made by silversmith Daniel Searles, of New Orleans. It's my opinion that this was the most important criteria for a Rezin Bowie-designed Bowie knife.
All that being said, I understand the lack of this feature on modern commercial bowie knives. Liability concerns, over accidents, or even use as intended, makes for nervous bean-counters, as well as upper management.
The only way to make something idiot-proof is to keep it away from idiots. Not an easy task these days.
Stupid SHOULD hurt! It always did for me....
