If you turn the lower part of the Rasierhobels, opens the upper part and you can insert the razor blade. I have bought this razor with the razor ASTRA Superior Platinum and can recommend this combination.
Detail Razor:
The razor blade does not wobble in it and thus a safe and gentle work is guaranteed.
The rear part of Rasierhobels is slightly heavier, therefore a pleasant wearing comfort and optimum weight distribution ensures
Optical me has the razor very convinced it's all very clean and well finished, I could not fault.
The price is very cheap for such a good product, the sound can be sampled at 100 package just under 11 and thus you once a long time cheap and very good to shave.
From me a clear yes to this product and 5 stars.
