I had the exact same experience last night with my first shave with the exact same blade from Vintage Blades. I felt like I was scraping the hair off rather than shaving it. Vintage Blades says all razors are honed by Lynn so I assume it is sharp. However, I just tried the hanging hair test on my razor with a strand of my girlfriend's hair and it did not cut the hair. The hair just bent when I pushed it onto the blade.

Is it possible that our blades are not sharp?

Is the hanging hair test nonsense?

I will try stropping and shaving again tomorrow to see what the outcome is.
