The steel for these beauties is one of the best high carbon steel which is available today namely the Carbonsong C135 steel.
As an example: Usual carbon steel for razors has 0.6-0-8% of carbon. Very good steel has 1% carbon. The razors you see here have 1.35% carbon.

So what does this mean?
The higher the carbon content the harder the steel gets. The harder it is the better is the mirror polish and the sharper it will be. It stays longer sharp, too.
Due to a new hardening process the hardness is way above 60 Rockwell. The back is a bit "softer" to give it more flexibility and to reduce the risk of breaking.
So the old equation: Old steel = better steel does not work!

All of the new forgings are superb shavers and the 5/8 are great for the novice and the pro.

All razors on this page have serrations at least on the lower side of the shank for a good grip and come in a Thiers Issard leather pouch.
The different prices occur due to the etching style, the polish of the blade and because of the material of the scales. The quality of the steel is the same!
Feel free to ask any question.
