If I would compare razors to music: aggressive = Rock. I don't care if I am scraping your skin because I am at a wrong angle. I want it all, I want it now! Gimme, gimme some beard (after midnight)! mild = Classical music. The instrument needs to be perfectly tuned: If it is not held at the right angle it will not produce result. Any scraping is refused (as at wrong angle the blade gets lifted up from the skin). With a skillful hand the result will be amazing food for the soul.
Agressive Classical Music: Alban Berg/Igor Stravinsky. Mild Classical Music: Bach/Mozart/Vaughn-Willams. Mic drop.....
