I ordered my first open comb last week, a nicely replated New from safetyrazors.co.uk.
I was surprised by it as it's very different from the usal safety bar and slants.
It's not as aggressive as I expected and does an amazing job at removing stubble.
Two passes of the New is comparable in the stubble removing stakes to 3-4 passes
of my normal razors. However I can not get as close a shave with it, smooth yes, even yes
but just not as close as I like.
On a mission to find something slightly more aggressive I've ordered a couple more
Merkur and Muhle open combs and will try the New with a few more different blades.
