I’m not sure I have the technique or the “boulders” for doing aggressive razor and the sharpest blades. This is why I may do the Feathers last.I personally prefer aggressive blades in my “aggressive” razors. Like feathers in my German37.
Now based on your feedback it really sounds like the wunderbar is worth the hype. I think I need to start putting a couple bucks away to pick this razor up.
