Artfully Martial said:Tactical knives, conversely, have grippy "modern" handle materials (G10 is the most obvious), or high tech synthetics, some use of steel or titanium is pretty normal. They have one hand opening or AO. They have one hand closing. They have locks.
That would certainly be the usage of the word "tactical" by the marketing guys. But the word "tactical" implies a martial proficiency, and that requires some minimum level of strength to really qualify. It doesn't have to be a "field knife" that can be used as a shovel, hatchet, pry bar, and screwdriver. But it needs to hold together if hit or kicked from the side or spine. Otherwise, it's just an ugly gentleman's knife.
