This thread isn't to slander anyone. We all know results vary from person to person. There are a ton of threads on which is the "Best" blade.....but i'm wondering which blades have given you the worst shave? For me....These two were pretty much exactly the same. Not sharp IMO and tugged like crazy on my beard. Crystal (these were horrible for me, felt like I was shaving with a rusty beer can) Merkur. So gents....what blades simply didn't work for YOU?
