oh boy! My kind of thread. Here's my EDC knife history.
In Chronological order from the oldest (bottom) to newest (top).
Bottom blade is one I picked up in Germany in high school. This was my 3rd real EDC knife and the 2nd oldest knife I have. Crappy 420 steel, has some rust spots on it etc. Very rare here, cheap and plentiful over there.
Next up is a Kershaw Ken Onion Blackout (if I recall). Torsion bar opening (original if you can believe it). Would have picked up in like 2005 or so. My first decent EDC knife, think I paid $40 or so for it.
The next is actually out of order now that I look at it. But its a Kershaw Emerson collaboration. Only tanto blade I have, picked it up because I never had a tanto style knife and wanted a cheap but decent one to see if I like them. I do, but I don't find it very useful. Still waiting on longer screws so I can flip the clip to the left side and carry it for utility work.
Next up is an actual Emerson, my first expensive knife. Emerson Mini-commander if I recall. Flat grind on the bottom side convex (if I recall) grind on the top, very very sharp (when maintained). Got tired of the tactical look, especially whipping that thing out at church etc., got me some looks. Paid a stupid amount for it , but this thing is bomb proof though and I've had it since like 2011. I believe it's actually my most expensive knife as I'm thinking about it.
Next up, Kershaw Cryo. Great cheap knife. This one is the G10 version. I think you can find them for less than $35 or so. Collaboration with Hinderer or whoever fancy pants. Great little work horse knife. Whenever I'm going somewhere that I may have to give up or leave my knife somewhere, I carry this.
Above that is my "gentlemen's" knife. Take it with me when I'm wearing suits. Or for birthday parties, Christmas etc. Nice knife to open packages with. MCUSTA is the brand, I forget the exact model. VG10 core with a softer damascus steel around it. Sharpens easily and well, but holds the edge very well thanks to the VG10.
Above that is a Zero Tolerance 350. Always liked these knives but was already passed the tactical phase, bought it to help someone out, but I still carry it in my left pocket most of the time. Don't use it to open boxes or anything. Guess its my SHTF knife. Hope I never have to use it like that.
Above that is my daily carry, DPX HEST (I believe) "Mil Spec" so it has the "Slepiner" super steel instead of the whatever tool steel they usually use. Has bottle opener on the spine, glass breaker on the end, and the frame lock can be locked in place while the knife is open making it "almost" as strong a fixed blade for when I feel like doing something stupid.
I've got a ton of other knives that I don't carry, fixed blades I've got attached to backpacks, stashed in the truck, or use around the house. You might say I like knives....
