It really doesn't take more than seconds to touch up steels like S90V and S110V..
I use S110V @ 65 HRC in the kitchen.... And I went 6 months without touching the edge, that's using it pretty much everyday and it was still very sharp, would still slice through TP easy. It finally started to lose some bite so I touched up the edge on a Spyderco fine ceramic file..... That's freehand, not a sharpmaker... It took me all of 10 seconds, like 3 passes on each side and it was screaming sharp again.
So if I have to touch that edge maybe twice a year, if that and it might take all of 20 seconds total edge maintenance...
