Since the testing is still in progress, we shall not discuss the heads for now (thank you guys for following my request on that). But I can give you some updates on other things.
The handles... The majority of you don't like the original handles, especially their appearance. After being pushed by
@spacemonkey42 (huge thanks to him for that), I completely redesigned them. After quite a few interesting and fruitful discussions with
@spacemonkey42, I came up with two completely new design proposals:
Straight surfaces of these handles would be glass beads blasted, but the cutouts would be done after the blasting. This would allow to achieve a satin surface finish with highly contrasting cutouts, which would also increase the grip.
Handles are 88 mm long, and with the new design, I also managed to get a great balance point, precisely where I wanted it to be. The new handles also helped to decrease the overall weight of the razor down to 88.2 g (razor blade included).
From now on, there is only an 88 mm long and solid option considered. Both designs will be prototyped and most probably only one of them chosen for further manufacturing.
Once again, I would like to warmly thank
@spacemonkey42 for his incredible input on the handles.
Don't bother about the handles rating anymore, as you already provided enough to make me realize that handles must be completely redesigned. Thank you, all of you.
Please keep in mind not to share any thoughts on the heads yet!
