Having scoured the old cutter block at least 10 minutes about my beard before I felt shaved me halfway, I am now ready to just over 3 minutes and the shaving is still to much better. If the blade holder now holds just 2 years, like the last, I am satisfied. (Of course, 30 is a bit much for such a replacement part. This one has but known before.) It is a pity of course, that you can not replace individual blades and shaving foil.
