First shave with the OneBlade this morning. Should I admit that I was excited enough to try it that I popped awake earlier than I normally would? No, I should not admit that.
Lathered up my brand new B&M Night Music (lovely scent, great slickness), confirmed that yes indeed, I AM able to remove the blade when need be (this was tricky at first), got it re-seated, and had at it.
The basic shaving ability isn't in question here. The OneBlade mowed down my whiskers readily, and with satisfying audible feedback. I wouldn't say it's as eager/efficient as, say, an R41 or what I imagine a Feather SS can do, but, especially going into the second pass, it ate up what was before it while seemingly determined not to irritate or nick. I also felt much more confident getting at problem areas like my chin and parts of my neck.
I found the shave surface very natural, and while the usual light pressure made sense, there were points where pressing in a bit seemed to help (I wouldn't add pressure through the whole shave, though). It's certainly more pressure than the super-light contact I've been working on with the Mongoose, and if I spend a lot of time with the OneBlade I'll be learning and entirely different set of manual instincts. The razor cruises around curves and forgives pressure: the analogy may be a (good) automatic transmission on a sports car.
Overall the feel is just different from my DEs, injectors and the Mongoose. It's got a relaxed, "no brainer," feel while still shaving effectively. It's too soon for any conclusions, but I already suspect if I were to have the OneBlade as my only razor, I'd miss the satisfaction of using (relatively) trickier, less "automatic" razors. Meantime, I'm gonna keep going with it over the next few weeks and see how it develops.
Two quick niggles: the design of the head makes edge trimming (sideburns in my case) trickier, and getting the hairs just beneath the nose on a WTG pass was awkward to say the least.
David : DE shaving since Nov 2014. Nowadays giving in to the single-edge siren call.
