Congratulations friend! Great 100th!
I’d like to leave it at that, but I’ll give some feedback, only because you asked for it. I don’t want to pick apart your shave, the reduction looked pretty good to me after the last pass; overall I’d call it a successful shave, however:
- SRs will feel different than the Feather and be much more audible. Some of your musings were headed in the right direction with this (grind, thickness of blade, etc). The Feather blade, for lack of a better analogy, is good until it quits, whereas the SR has more of a progression of edge feel. Technically, once you know your edge preferences, with constant touch ups on the edge, you might never feel the edge degrade too badly.
- Lather looked too thin and airy.
- By the final pass your strokes had shifted to a more relaxed angle, your confidence definitely grew within the shave. The first two passes your SR was nearly flush to your skin, which is not bad if your blade is hyper-sharp, but yours may (I have no idea) not be, which is why you perceived more chatter and skipping. Otherwise your technique carried over well from the Feather I think.
- Tugging in an SR means edge issues most likely. It’s possible that the edge was degraded a bit the last time you stropped it or, as you researched, Sir Stark my have not put a good edge on it (that seems to be a theme with a number of makers, I don’t know why). Your idea to have someone check/refresh the edge on it may not be a bad idea.
Be confident that it really was a good shave Dave! These improvements are really only minor, you are well within the realm of passable experience, training wheels no longer needed!
