The blades I have not yet tested.
Who wants to try the blades should order them in time.
I'll take from time to time updates to the blades.
Update 1 Dorco Blade: I was able to use the sword for 4 shaves. Sharpness was ok.
Update 2 Super-Max blade: First Shave: blade draws something on the hair. Does not seem to be quite as sharp.
Second Shave: Sword twinge strongly to the hair. The shaving is uncomfortable. Will the blade not used for another shave.
Update 3 Astra Blue: 4 times shaved. Okay. Better than Super-Max. but can not serve up Dorco.
Update 4 Astra Green: 4 times shaved. Best blade so far for me.
Update 5 Shark Super Stainless 2 shaves. Zips. Unpleasant blade.
Update 6 Shark Super Chrome 2 shaves. Better than the other Shark but not the yellow of the egg.
Update 7 Derby: 3 shaves maximum. Better blade but not the best in the package.
Upadte 8 Mercury: The Mercury blades 3 times used. Very good quality
Update 9 Feather: use 3 times. Very good.
Conclusion: Feather, Mercury, Astra Green, Dorco, Derby are useful.
I still have the tested Personna blades, which are not included in this package. The Personna are the top next to Feather. My Opinion.
