I got a tuck of these with a recent razor purchase. I didn't use them right away and kept on with my Astras. Did a three pass with my Pearl yesterday on Astras and got a very close, great shave. Not much stubble today but wanted shave for the holiday. Used a Poli in my 34c and went full BBS. It was indeed sharp and very smooth. I was pretty amazed as I usually can't get shaves like that two days in a row. I'm going to give them a whirl in all my razors.
