I’m 21 shaves in with the same blade/razor combo AND I’ve stuck with the same soap most of those shaves. I’ve been working on finishing off my first tub of Ghost town Barber as well as giving this Kai blade a good longevity test. I’ve noticed a few shaves have felt a little less comfortable, as if the blade is tugging or pulling some but for the most part those shaves are few and far between and possibly the work of the lather ...or at least as likely to be the fault of the lather as the blade. BUT, the closeness on the neck dropped off a week to ten days back. It may be connected to the tugging and my adjustment to approach or pure blade but I have had to do more clean up on the neck than typical with these type of blades and more than when the blade was fresh. Other than the appearance lack of efficiency the shaves are still pretty much the same closeness with similar longevity. The comfortable has been rock solid the whole time, the Kai captain titan mild is a really mild feeling blade, very comparable to the pro guard in my opinion.
I’ve taken to stropping on cotton and doing some laps on diamond pasted balsa with hit-n-miss results. Mostly the difference seems to be positive, it has or appears to have helped coax more life out of the blade. Today I found that my old Japanese Schick folding razor has a perfect geometry for stropping a blade on the balsa strop so I loaded the blade into it and ran the blade 10 times each side on 0.1u chrome oxide, it looked nice when I was done but the real test is tomorrow’s shave.
I’m hoping to finish the GTB soap off by the end of the month so I can move on to new soap,and a new blade.
