If any of you folks have carried a Delica or Endura for several years, how have the knives held up to rigorous use over the long-term? The E4 is one of my favourite platforms but I haven't owned one long enough to see how the internals have degraded over time. I dunno....just something I've been thinking about today. Cheers for whatever input I receive!
I carried a Delica 4
(edited to change the D2 model to D4. It was the second Delica model I had carried, but it was a D4) for 15 years when I worked in a warehouse, mostly the same black/VG10 saber ground one. I still have it clipped to the back of a small Gerber multi-tool pouch in my car console. My wife and I each have a ZDP-189 Delica as well. I can say that they've all held up well and worked fine,. All of them show some their use, but that's to be expected. They're all over 10 years old. I have no regrets about carrying one to work.
I've used it to open boxes, carve styrofoam for packing, cut pallet strapping material, and even (don't tell anybody) stuck the open knife into the bottom of a packing box over my head and used it as a lever to move the box forward until I could reach it from a cherry picker (thank you for a dependable backlock, Sal). I've also dropped it from 20 feet up onto a concrete warehouse floor and the only thing that happened was that it got a little dusty (I really like FRN for a work knife).
I carried it to the beach near St. Simon's pier a couple of times, got it wet in the Atlantic, rinsed it out and dried it, and today you'd never know it was in the ocean. It's like a Bic pen. It's not pretty, it's not fancy, it's not "cutting edge" (ha, ha. See what I did there? I kill me), but it works today just like it did when I bought it new.
I know I sound like an ad for Delicas, but all this is my genuine, long-term experience with them. And that's why my carry knives are almost always Spydercos... they just work, time after time after time.
