Price doesn't have to be a determining factor here. A tactical knife needs these characterisrics:
1. Good blade configuration. Spear-point, tanto, drop-point, plus edge preference (V-grind v. chisel grind), are all viable choices, as is blade finish (matte, black or polished);
2. Blade material. Although premium steel is great for edge retention, it's not necessary for tactical use. Neither are gimmack steels like San Mai;
3. Lock. There are many reliable locks, but some are stronger than others. I recommend the axis locks or the lock backs.
4. Handle. This includes material, configuration and strength. A good tactical handle should offer a good grip that prevents the hand from sliding over the blade if it hits a solid target. It also should not conduct heat or cold and it should be "grippible" even in a gloved hand;
5. Blade length. This is the weak link in many tactical knives. I can't believe how small some of these knives are. One reason I like Cold Steel knives is that 5- and 6-inch folders are available.
6. Finally, speed of opening. A tactical knife should be sharp and quickly deployed.
All things considered, I like the Cold Steel Recon 1, primarily because of its fine serrations. And if the Recon 1 were made in a 5-inch black blade, it would replace the 5-inch Gunsite I carry now.
