From my limited experience with this handle shape, it is not really functional.
The titanium alloy finish is very smooth.
Combined with the lightness of the handle and the progressively reducing diameter as you go up to the M5 thread, the thing does not work for me personally.
This one herebelow may work better, and I should have opted for it (it was actually €3 more but I refused to pay the extra because all I wanted was the head...)
Incidentally the razor head works very well, I shaved this am and it is a great shaver (mild of course).
It is astonishing how good the Chinese can be when tooling and machining comes about.
They call this thing "EDC", in almost everything they do they can seldom get proper brand or model names right.
The head geometry is supposed to be 'open comb' on one side, 'closed comb / solid bar' on the other - but the way either side shaves has minimal difference in aggressiveness.
To have such a top & bottom cap plus a handle from Ti alloy all for less than twenty quid delivered, who would have thought some years back...
