So today, just for the halibut, I decided to try one of the Shark super stainless I've had in my stash for ages (along with the chrome and platinums). Loaded it up in my Razorock SLOC and proceeded to have a damn fine shave, quite possibly my best to date. Considering all the disparaging comments about these blades this really goes to show YMMV. Since I was already in an experimental mood I decided to try my Merkur Futur along my jawline. That's one of the spots that give me trouble along with my neck. I've used the Futur maybe twice since I bought the thing. Anyhow, I set it on 3 and damned if it didn't shave my jaw perfectly smooth in one pass! Guess I'll keep it after all.
