Let me tell you the nuts and bolts about cowboy knife first…

The ethnic origin of cowboys and why knives were essential

Taking a look at any cowboy-themed movie and the image of a fixed blade knife always appears to be bigger than life. We often see large-scale bowie knives that are cumbersome and menacing akin to what Crocodile Dundee would consider a knife. It’s simply too comical for practical reasons as you will find out.

The real truth to the matter goes back to early American history and the European roots that reveal highly skilled cattle drivers.

As far back as 1725, the term “Vaquero” originated in Spain and describes the activity of managing cattle through riding on horseback. The roots and origins of this word likely derived from Arabic words that were documented in Latin as the word ‘Vacca’. This may have been derived from the Arabic word “Bakara or Bakhara” which translates to the word heifer, which we also use as a word for young female cattle.

Now, these Vaquero’s were an essential trade that moved cattle through New Mexico, Texas, and Mexico City. Their essential knife was a rather thin blade that had a sharp edge. It was used for preparing food and cutting meat from bones, cutting rope, and working leather. It was seldom ever used as a weapon.

Many veterans chose a cowboy lifestyle which was a booming business for those who didn’t want to return home. The knives they carried were the Confederate Bowie knife with scabbard or the Union soldier bowie knife.

Both sides used Bowie knives yet the Confederate side had more effective use of this weapon. It was large enough to be used as a hatchet and was great for chopping through wood and branches.

The D-Guard Bowie knife was the most common.

Many of these newly freed slaves found lucrative careers as black cowboys, cowboy trail cooks, rodeo entertainers, and fit perfectly into the ‘Cowboy Code’ that other cowboys all practiced.

  • Ex-sailors from the Gulf of Mexico

Living life on the high seas was hard work for many who traveled the often dangerous trade routes within the Bermuda Triangle. But it might give you an idea where famous cowboy trail songs originated from since ex-sailors turned cowboys brought this tradition with them. Their favorite knife of the shipping trades often included the Cutlass which is a short saber.

It may have evolved further into the modern-day Machete and was more favorable in Mexican and South American territory as an agricultural tool. It can also be traced to ranching and cattle farming where large fields needing clearing for cattle.

Why fixed blade knives are popular for cowboys

Fixed blade knives are a common sight for most cowboys and are mainly used as multi-function tools. Since thunderstorms were common in the mid-west and on the cattle trail many cowboys would ditch their knives, and metal gear at the first sign of lightning in the area. A lightning strike while wearing anything metal could prove to be fatal for cowboys in the old west.
