Very sharp and durable, but not quite so gentle

I have to try in my safety razors
already used many blades, but when it comes to sharpness
the Feather blades, at least among the German market
available blades, the best that I know. If you as a
Beginner wants to work with this blade, so that's for sure
possible, but should urgently needed with the caution and
absolute avoid pressure on the skin during shaving
!! happen If this is taken into account, one really has an
good and very durable (depending planing up to eight shaves)
DE-blade that offers good value for money and
from my personal taste point of view only on the, not in
German trade available, Personna Medical Prep. topped
is acting just a little gentle when shaving.
