These are great blades for Henson AL13+++. I do agree that in other razors they can seem "mild". In a Henson I rate them close to a Gillette 7' Oclock yellow. This is the only blade I'll use in my Henson. I get smooth shaves with one pass and touch ups.

Probably the dullest blade I've used so far in the DE89.

Supposedly, these blades are aggressively sharp. They're not. They're garbage blades, and they're the ones that Henson Shaving promotes. I have a 1 month old, plastic 4 blade razor that cost me $2 for a dozen of them, that shaves better than a brand new RK blade. I can take a blade and bend it in half between my bare fingers. They're garbage. By a Remington, or Bic, or Feather blade. These blades wouldn't even scrape paint off glass. Junk.

I bought a 100 pack along with the Henson since these are their recommended blades. For a single shave, they’re fine but I can’t get more than 2 shaves without tugging. I have better luck with Astra green which was their recommended blade before the RK.
