Since you posted pictures of two of my favorite tactical gear: 1) Benchmade Stryker 910s early model (my all time favorite knife), and 2) HK VP9 (all H&K guns are awesome), I will enter this debate. American tanto knives are my favorite tactical knife design. I use them for all around chores and there’s not any drawback that other people imagine. The tip is made for piercing, but can cut small things with finesse also, and it’s so easy to sharpen. Also, serrated blades are thought to be made for cutting rough materials, which they do fine, but they also cut soft and common material with ease. And because a serrated blade has increased edge surface, it tend to last longer. People also speaks of difficulties to sharpen, but if you are careful and develop the skills, a spyderco sharpmaker can do it just fine. And you have always the option to send it to the maker (benchmade does it for free). Right now I’m carrying a SOG Auto Clip serrated tanto in BG-42 that has been with me for lots of years, and been used for any task you can imagine, and it’s still at the front.
I would also like to share some of mi Benchmade strikers and a gorgeous ZT.
