I have a Busse Nuclear Meltdown SF Natural Outlaw. It is unconditionally guaranteed forever. If I somehow manage to break it, Busse will fix it. It’s made of a special magical steel called INFI. I’ve used it to shave and I’ve used it as a prybar. You can hack through cinder blocks with it.

It is the most perfectly beautiful and functional object I own.
I want its big brother the Combat Mistress, and will own one someday.
For EDC, more often than not, I find myself carrying the Spyderco S

It’s reasonably priced, has a good cool factor, is nonthreatening and incredibly light. Very useful design, not compromised by the skeletonizing.
For big folders I have a lone wolf Harsey D2 and a Benchmade Rukus, which are not particularly useful, though they are cool.
My other main EDC is a Benchmade 890:

It’s really really nice, but a little heavy and threatening in appearance. I like the assisted opening and the glass breaker feature at the base.
I have a Benchmade 580 which I don’t really use:

I have a Benchmade Kulgera axis lock which I’ve carried and beaten up and abused. I’m a huge fan of the Axis lock

Beautiful knife.
Spyderco Endura 4 ffg which is nice, but I don’t ever carry.
I have a benchmade Osborne 940:

This is probably the perfect Every day carry knife, but mine got ruined when I lost in the backyard for a winter. Mine’s workable right now, but I’m ashamed of what I did to it, and don’t carry it.
I have a a bunch of other stuff, swiss army knives, Kershaws, a Cold Steel stilleto, some bucks, an RTAK 2, Sog Flash 2 that I don’t like very much, some goofy pocket knives that I won’t mention, and a pretty broad collection of multitools.
I always have a multitool in my briefcase, one in each car, a smaller one on my keychain, and I always carry a knife for utility purposes. I think it’s unreasonable not to have one on your person.
