Ok, not so much a knife blade shape as it is a complete knife, the Bowie knife is probably one of the most famous and well know knives. It is a large fixed blade with a clip point designed for fighting. The knife was designed by James Bowie and improved by bladesmith James Black.
Jim Bowie was a 19th-century American pioneer legendary for stories about being a great fighter. He became famous for one fight, in particular, the Vidalia Sandbar Fight. This fight broke out after a peaceful duel between two gentlemen ended in a draw. One group that was present had to settle a “difficulty” with another.
The fight only lasted a few minutes but it left two people dead and several wounded. By all accounts, this would have made an epic movie fight scene. Jim was one of the wounded, he was lucky to survive since he was in the cross-hairs of many in the crowd.
Fun fact – From Wikipedia, a duel is an arranged engagement in combat between two people, with matched weapons, in accordance with agreed-upon rules. In the early 1900s duels were outlawed because most of the time they involved military officers. Military officers cost lots of money in training and education, the government wanted to stop wasting this money when they were killed by their own side.
