I have probably what you would call a light to medium beard, sensitive skin on the neck. Only shave every other day. Anyway these blades are dull. Not smooth, lots of tugging and SCRAPING. Will never use these again.
A very dull blade, not made for thick beards like myself, little box is cool tho def a collectors box, gave me a few nicks, i would recommend bluebirds there sharp and longevity is fantastic get about 6-7 shaves, this blade just plain sucks.
These excellent blades are made from Swedish stainless steel and get the job done. While I did receive about 4 nicks when shaving and little razor burn, I finally experienced a close and clean shave. It only took me 3 passes to complete my shave. The blade sang as it passed over my skin and I highly recommend them. Only problem is as of now I have only found one vendor for them.
