Well, I reckoned I had enough stubble to give the Featherweight a go this evening...
I used a Gem blade that had already had some use - I'd already done 2 or 3 face shaves with it, and I shaved my head with it last week (using an Open Comb Micromatic).
And the shave was really good - WTG and XTG passes, plus a bit of ATG buffing in a couple of areas, left me near baby-smooth.
The Featherweight is clearly more cheaply made than the earlier models, with pressed metal parts and a moulded plastic handle, but that doesn't mean it isn't a great razor. It seemed modestly aggressive without being excessive, and is quite nicely balanced. All in all, I was very impressed by it.
