Blade Feather ProGuard 19th Use.
Shave with razor paired with the well-used blade was still good, still smooth, comfortable & efficient enough but just not as silky when new.
Personna Red in a Merkur Progress. The blade is the one I loaded into the razor at the beginning of May and neglected to swap at the first of June, so it probably has 3 shaves on it now after today. Still sharp and able to mow down beard without issue.
