Well, this is an interesting topic and got me going back through my Imgur files to pick out a few knives "built like tanks"--IE beefy, hard use models. My Hinderers all qualify, for sure, and my CRKs, save my Mnandi, are all really solid and built to put-to-work. Some of my ZTs, present and former, qualify as well as the odd one here and there. No flies on my Shiros either as at least a couple of them are in my regular work rotation.
The thing is, I don't usually find myself in situations where I need a knife to perform a task better achieved with a proper pry-bar, ax, saw, etc, as I usually have those tools handy at home, work, in the woods, or wherever. My knives tend to be used to cut things
in the more conventional sense.
Anyway, here's a few samples of knives built like tanks but used more like knives. This beast came to me like this--
--but ended up a much better "matter separator" (nice term,
@Shorttime ) after a trip to Josh at REK.
This Les George ZT is a big tank of a folder as is its slimmer cousin the WC/LG Eagle.
Here's one I sold a while back, the mini-tank 0350. I kinda miss it, but it never got much carry.
What could be a more tank-like folder than one with a handle cut from a solid block of metal.
One more for now that's both one rugged piece of gear and a really good cutter too.
I'll dig out a few more later....
