What is a Tactical Knife?
- Synthetic, grippy handles (usually)
- Non-reflective blade coating (usually)
- Designed for hard and/or quick use
- Aesthetics invoke military purposes
- Spyderco founder Sal Glesser once said, a tactical knife is any knife you have with you when you need a knife.
- Some say custom knifemaker Bob Terzuola made the first tactical folding knife, while others say Ernest Emerson did.
- Maybe it’s all a marketing gimmick!
A Brief History the Tactical Knife
The term “tactical knife” was coined in the mid-1990s to define a look with certain characteristics. Regarding fixed blades, the characteristics included a non-reflective blade coupled with either no guard or one of stainless steel. Some still use brass and others incorporate titanium for guards, while some use black zirconium. Currently, zirconium’s price deters both makers and collectors. If the price comes down you can expect to see more zirconium for guards. Handle materials should be synthetics, including but not limited to Micarta®, G-10 and carbon fiber. However, these three are far and away the most popular handle materials on today’s custom tactical fixed blades.
Over the past century grip materials have evolved from wood, leather washers and even cast brass and aluminum to the current synthetics. In the mid ’90s, primarily Micarta was used. Linen, paper and rag Micarta were the staples of the day. G-10 then came along, offering more colors and configurations. Over the past five years carbon fiber has increasingly become a handle material of choice.
The non-reflective blade was accomplished through several methods, the most common being a belt satin finish. As the name implies the finish was applied simply by using a sanding belt. This gave the blade a good-looking surface that was not reflective.
Key Tactical Knife Feature: Non-Reflective Finish
Another method was sand blasting. While providing a non-reflective finish, this technique had a problem. The sand created micro pits in the steel. The pits held moisture, leading to blade rust. That led to replacing the sand with silicon glass beads that did not leave pits and produced a more even, flat-gray, non-reflective finish.
