There's a couple of REALLY cool things about the Biohazard that aren't immediately obvious from the pic.
#1, that whole area of grip around the pivot and ahead of the first finger notch is NOT meant to be grabbed, or even touched. And that means that your finger is always well clear of the linerlock release tab, solving the single biggest linerlock problem, that of accidental release in mid-fight as can happen with something more "AFCKish". The release tab on the linerlock is only on for "forward end" of the notch, away from your finger.
That also effectively gives you an additional inch of "range" without stretching the blade.
It's absolute *genius*.
The blade is of THICK stock. Not quite 1/4", but a lot closer to that than what you usually see on folders. This is necessary due to that "weak spot" where the hook makes the blade thinnest. I'm not saying it's weak, it's not. It's a superb "hooking/tearing/ripping" pattern but it doesn't have enough heft for "smashing" attacks so the blade pattern is fine for the application. If you tried to stretch this to Outsider proportions (9" from base of choil to outer tip and 1/4" stock" the Biohazard pattern might fail on a heavy smash but in this form, no way.
Awesome piece. The only downside is probably the chisel grind but even then, it adds overall strength and since it's NOT a utility knife AT ALL, frequent resharpening isn't going to be an issue.
Last question: what's the contact information for this guy? Dunno if I can afford one just now, but...b'gawd it's tempting.
