3v: hard to find on production folders
CRUWEAR: harder to find on production folders
4v: even harder to find on production folders
Elmax: you get the idea.
Edit: let me clarify: in your price bracket
Not impossible of course... Adamas is CRUWEAR now, but I read some bad articles about their performance so havent bought one yet. Also, s*** tends to get stuck in axis locks especially dust and stuff, making them not my first choice for "hard use".
Based on your choices, it seems you want a small-medium hard user with an exotic steel with a decent toughness? Did I get that right?
Try the Spyderco Native, especially one of the sprints in Rex45, LC200N, M4, Magnacut (wink wink). If you want larger, go Native Chef (misspelling on purpose).
Spyderco Endela, Endura also comes to mind. The new Straight Stretch in K390 is my 2021 favorite release from them, AWESOME knife. FFG means awesome slicers, and K390 in my family use, has more than enough toughness as a folder.
Shaman works too, but I think you might find it a bit big, heavy, and underwhelming.
ZT also makes some great light hard users.
Sounds like a CS American Lawman or similar is perfect for you. AUS10a is tougher than S35VN in my experience, just FYI.
Some of my thoughts about "hard use":
Dergyll order of operation
1 - get a fixed blade
2 - backlock (I count triad lock in here)
3 - framelock
4 - everything else
Say no to assists, springs, etc anything that complicates a knife mechanism. I've rusted my fair share of knife internals. Also, some of the best hard users, are not always the prettiest.
Thanks for reading my brain dump!
