My research indicated that Open Comb razors (such as the 1904) were more "aggressive" than closed comb razors (such as the Merkur HD). I would say based on my limited experience that is true. However, this particular razor for some reason sits more towards the mild end of the spectrum.
I found that my face liked the razor almost instantly. The first few shaves were close and comfortable, and you can't ask for more than that.
I also found that this razor is TINY! It's much smaller than you think it will be! I don't have large hands, so keeping a hold of this razor and manouverability are a cinch for me.
Overall I would say this great razor is suitable for a beginner because it's easy to learn technique with but honestly, any shaver, regardless of experience, will be able to get a fine shave with this.
I have heard some minor gripes about the handle. Looking at it you might think that it might not be that great in the clinches, but even with wet fingers, in the middle of a shave, I have yet to lose grip.
What's more, it looks great!
