I had one for a few years. Used the hell out of it the s30v and was my first experience with that steel. The factory edge lasted through so much abuse cutting up everything from slicing/removing entire carpet interior from multiple classic cars(my job as a fabricator/restoration), digging out messed up aluminum & brass repairs, and generally banging the crap out of it! I tend to USE my tools and not lightly! After about six months, I used my newly acquired whetstone “skills” to put an edge back on it. Tried a new edge type on it(convex) and although it was still beast, didn’t Last as long as the factory edge. That’s where I learned the importance of edge type and angle to different steels, heat treats, etc. The Volli in s30 served me so well, I’m a little surprised it’s not as appreciated as it should be imo. Just picked up an m4 freek and looking forward to seeing how long THAT withstands my abuse!
