my Merkur 34C. I did my normal every day beard prep, changed nothing and it wouldn't cut the hairs. The darn thing was scraping across my face not cutting anything. After 3 short strokes of hair being left behind I changed blades to a PolSilver Stainless (brown) and had no issues. Shaved like butter.
I've used the GSB in a Slim in the past and although it wasn't the best shave i was certainly able to use it for a whole shave. In my 34C today..no way.
Funny thing is i've had similar issues in the past with blades & 34C. Bics gave me the exact same problem and most recently Sharks. I think it's just one picky razor. And i'm starting to get a little irritated with it.
