30th day ( 3 passes a day) on one of my small stash of Personna 74's. Still just as smooth and sharp as the very first day. I shall press on until it begins to drag, then move it to the spouse's razor.

Personna Lab Blue/Med Prep? 1st use
Wow..!! What a super nice smooth and comfortable blade! In combo with the razor gave a excellent shave!
