I became aware of a behavioral pattern of mine some time back. When I'd get sort of anxious or uneasy about something, I'd instinctively reach for one of my knives and a stone. Didn't really matter if the knife actually needed sharpening or not - I'd just pick them up and start honing. Part of it, as my rational mind told me, was about keeping my hands trained to the process. But after a point, I realized it was just as much about giving me something to focus on, to take my thoughts away from whatever bothers me at times. In that respect, it really does relax me. And the bonus is, when I'm in that frame of mind, I notice my additional focus on that task pays off in the quality of my sharpening as well. Some of the edges I've been most proud of have been the result of my 'stress relief' sessions with the gear.
Prior to my learning freehand sharpening on the stones, I did often spend a lot of time with one of my strop blocks and a blade, which I did find relaxing as well. Oftentimes, it'd be just after a good meal and with a glass of wine by my side. Great way to wind down in the evening, while watching TV in an easy chair.
