When it comes to a good fighting knife, I typically look to Ka-Bar for a good standard. The decades of experience in war as a fighting/utility knife has given this knife a good amount of seniority, as well as a legendary status. Heck, this knife is basically like the 1911 of the knife world; most experienced fighting knife that is still a standard for combat fighting/utility knives.
Cold Steel is a knife company that is generally known for their entertaining videos and demonstrations on how tough and durable their knives are. They often video themselves torture testing these knives and using them to do somewhat outlandish tasks with them. I personally feel like Cold Steel has a very vast selection of knives that span from the highest of quality to the lowest and worst quality. The company is one of my favorites when it comes to tanto blade designs, though. The GI Tanto is a no frills tactical knife that is designed to be capable of doing everything a soldier might need a knife to do.
I can't really speak for anyone else, but I am really into Ka-Bar knives for their versatility and legendary combat record. When I think of a fighting knife, or a combat knife, I imagine the leather handle Ka-Bar knives that Marines had strapped to their web belts in WW2. Ka-Bar has a pretty extensive line of knives that take after the original design, but with some minor improvements or compromises. The Ka-Bar Fighter knife is a knife that caught my eye right away when I saw it in a knife cabinet, and I had to have it. Now the question is whether the knife actually has any practical uses behind it.
