This morning, I had a Personna lab blue with 4 shaves on it in my Futur. Very nice blade, so much so that I ordered 100 from WCS that came in last Friday. The 1st pass was a bit tuggy, so I changed it out with one of the new ones. I did notice they were marked differently, but didn't think much of it until later, but after the other 2 passes, WOW! New favorite blade!(well, gotta see what the next few shaves bring). I used to have to do a 3 pass and then some blade buffing to clean up my neck, but not this time! Best...BBS...EVER!
Here's a shot of the two blades. The one on the left is the old one. Did WCS accidentally send me 100 med preps instead of lab blues? The new box says "25% sharper" on it.
