Didn't mean sound flippant before. I was just a bit surprised by this statement. Not sure why anyone would conclude that a Bowie knife was designed for stabbing. I read one author in a historical context....can't remember if it was an old magazine or newspaper article....anyway, he concluded that the Bowie knife was designed for stabbing because it featured a cross-guard. This was someone who clearly didn't understand how a blade is used. The longer a blade is, the more likely you are to have "blade on blade" contact. When you have "blade on blade" contact, there is a real and likely danger of the opponent's blade sliding down and cutting your hand. That's one thing a cross-guard protects against. When doing a thrust and meeting resistance, there is a real danger of your hand sliding forward from your handle onto your own blade. That's the other thing a cross-guard protects against. Military sabers are NOT designed for thrusting, and yet they feature cross-guards. So that old article's author was clearly mistaken.
Historically in the past, any big knife carried around for fighting or self defense was called a "Bowie knife." Design features could vary pretty widely. Some didn't have a cross-guard at all. One version was double-edged and essentially a big dagger. It was sometimes called an "Arkansas Toothpike" as well. I would tend to agree that this one was designed primarily with thrusting/stabbing in mind.
But over time a "Bowie" knife was really seen as a knife with a pretty classic design. It had a deep belly, a clip point, an off-center tip, and a cross-guard. That deep belly combined with the curve in the blade to that off-center tip was meant specifically for slashing and snap cuts. The clip point was meant specifically for back cuts. That off-center tip was meant for thrusting from wider or curved angles. It was true fighting knife design meant for multiple aspects of the fight....not just thrusting.
