You see my 2020 review.....best blade for me ever, and actually the only blade I use. Sharp, consistent....every blade in 2 years perfect! Well 2 years later and I figured Id stock up since they are made in Russia....may not be able to get them if Putin keeps screwing around! I still have alot of my 2020 batch left, but pulled 4 to try out. I tried 3 different soaps, face lathered & bowl lathered, badger brush and top notch synthetic used. Been shaving for 40 years. These blades immediately reminded me of Derby....Dull...Chatters Galore...no pick up of sharpness after 1st use...left a few spots actually irritated. I thought I might have received a fake "knock off" blade, as Ive seen guys post. They look legit, packaged correct, wax dabbed wraps, ink looked correct, but these are definitely not the same Nacet blade I bought 2 years ago. Glad I wont need them for awhile....
