I leave my stones at home, I rarely sharpen my own stuff at work. On the other hand, I often find myself sharpening at work, mostly showing/helping my coworkers how to do it.
I'm a tournant now so I'm roving around a lot, rarely have the free time. Even if I finish all my prep, it's very much expected I lend a hand to a fellow cook in the juice.
I did touch up one of my knives on a coworkers shapton 4000 glass stone last week. Just wanted to try it out, plus I had to mise out a few L's of scallions. We use way too much scallions at work, it's comical. We throw it on everything.
I was surprised at how fast cutting the glass stone was. It's the first truly splash and go stone I've tried that lives up to that claim. Most splash and go traditional waterstones still benefit from a 10 min soak imo. Glass stones do feel kinda dead when you're sharpening, that's the one complaint.
btw Dispossessed, where do you work? Kyo ya? Kajitsu? Sugiyama?
