I often see messages on this site regarding various Personna blades such as ones made in Israel, lab blues, and medical prep blades. I have appreciated reading those messages and also using the lab blue and medical prep blades in particular. However, I have been using made in England Personnas for about a month now. I have personally found them to be close to on PAR with the lab blue and medical prep blades in regards to sharpness and smoothness. I thought some folks on here may appreciate seeing this blade and reading about it. Have a good day, Mullard. See below pictures.
