I used an S30V Mini Grip at work for more than a year, working in a warehouse environment, and have really put it through it's paces. Cardboard, plastic strapping, wood, shrink wrap, I use my knives hard, and having carried a knife constantly for the last 20 or so years daily, I can attest that S30V is a great working steel. It holds an edge longer than a Buck 110 in 420HC, but is harder to sharpen. It holds less an edge when compared to D2, but D2 can be a bitch to sharpen if you let it go too long. I have used a mini grip and Spydie Native both in S30, and neither chipped. I have a William Henry in ZDP, but it being a gents knife, I have not put it through any hard work. I can tell you, though, that it is the sharpest knife I have ever owned, probably due to edge geometry, but that thing is so sharp it scares me. I've opened numerous letters, a few plastic clam packages, beef jerky packaging, actually a lot of smaller and a few bigger/tougher things with that W/H, and I've only ever stropped it once. Comparing S30V to a Yugo? I don't know about all that. I DO know, in a real world work environment, it holds up as well and better than all other steels I have used.
