The heyday of the Bowie knife was in the 1830s, '40s, and '50s. It was apparently on its way to becoming a thing of the past by the Civil War because the revolver was becoming widespread.
The knife James Bowie used in the 1827 Sandbar Fight was indeed made for him by Rezin (pronounced "Reason"). But I was under the impression that a later knife or knives used by Bowie were forged by James Black.
Correct. The knife Bowie used in the Sandbar Fight was a butcher knife. But apparently by the time Bowie fell at the Alamo the classic design was being used.
Apparently, there were, broadly speaking, two styles of employment. One was based on saber fencing and the knife was held cutting edge down. This style was probably a bit more refined and was likely the style used by the Creole dandies (they even had schools for it).
In the second style the blade was held cutting edge up. The back could be used to block incoming slashes and you could rip up when withdrawing a thrust (can you say disembowelment?). I suspect this was more of a rough and tumble style. I can imagine it being used by flat boat crews and the riverfront crowd.
That is a good example of the classic design. There were variations.
I read that the late Bill Bagwell, bladesmith and Bowie historian extraordinaire, speculated that what we think of now as the classic Bowie design, may have developed from a cut down naval cutlass used by Jean Lafitte's bayou pirates.
You mentioned the weight of the blade. Apparently, it was almost impossible for two men to go Mano a Mano with Bowies and not have both of them come away cut up, sometimes seriously, because of weight of the blade made stopping it or totally avoiding it difficult. If I recall correctly, in the book Bowie Knife Fights, Fighters, and Fighting Techniques, most of the fighters studied and documented had exactly ONE Bowie knife fight under their belts, although one man had three. It seemed to often be a case of the loser died and the "winner" came away hurt.
The most notable Bowie knife fight I am aware of occurred in the legislative chamber of the Arkansas State House in 1837 when two members of the legislature disagreed over a bill. One got killed and one got cut bad. The "winner" was tried and acquitted.
I've seen Livereatin' Johnston's Bowie knife on display in the Cody, Wyoming museum. Interestingly, it doesn't have a crossguard and the clip point is not as pronounced as some other surviving Bowies. But some who have examined the knife believe it shows evidence of once having a crossguard and a longer clip point that may have been broken and sharpened back.
