I had a Pakistan-made survival knife with the hollow handle. 420J2 steel, I presume. That was a LOT of work to re-grind the edge to something useful, and even after I did, it didn't stay sharp. That's one thing to keep in mind when buying a knife: the factory edge grind. If it's not good, you're in for a LOT of work to correct it, even with coarse diamond stones. The only thing that would help would be some type of motorized sharpener.
Much as I love them, my Swiss army knives need (comparatively) at lot of maintenance. They need the pocket lint cleaned out of them maybe every couple weeks' worth of carry, and the steel is on the soft side, so it needs pretty frequent re-sharpening. It's only a couple swipes on the Sharpmaker, so it's not DIFFICULT maintenance, but it is frequent. The small 58 mm Victorinoxes especially need a lot of sharpening, with only 1.5" of sharp edge, each inch needs to do a LOT of work! On the other hand, those models have the backsprings inside, so they keep their snap even when full of pocket lint.
I bought a used Benchmade Arcane and it was from the older days, when they still sharpened by hand. It had a wide edge grind and I was dreading having to re-grind that super-hard S90v. Since it was also full of lint and missing a pocket clip, I sent it to Benchmade, who promptly corrected all of the issues. Whew, dodged a bullet on that one!
