I have been at this a while but haven't really tried that many blades.
I have issues trying to get a lot to work for me so i have gotten a nice big set of samples of some of the more popular plus some less popular that i gather may work for me.
I have been less than happy with most of what rapira have to offer. My go-to for a long time has been shark stainless.
There are several previous threads on my ongoing trials. Most have not ended well
I will give each of these blades a decent shot in several razors and give my opinion of them as i go. Hopefully i can get some better results.
