I used to only shave with a str8… probably a 3 year stretch. Then it kind of lost its novelty and I’ve been happily using DEs. But it’s good to keep my muscle memory. This is a dubl duck special no. 1. And I must say, I honed it to near perfection on my Norton 4K/8k… that’s all I use besides a pasted paddle strop before the shave. this blade shaved like a dream. Will probably keep with it maybe weekly to maintain that form. It’s been a minute since my last str8 shave, so was real happy with how this one went— super smooth, not a single nick.
