Thanked: 3164You can't tell by grouping razors, either by country, locality or steel.
For instance Sheffield steel is said by many to be soft, but it can be very hard indeed, even in some of the older brands.
Swedish steel is generally accepted as being hard. BUT Sheffield steel was forged frm Swedish iron ore (mostly).
The main factor thzt determines the hardness is how the steel is tempered, so we can have a very hard but brittle steel, a strong but resilient spring steel, a hard but impact resisant tool steel and a soft easily worked steel - all from the same starting alloy.
Unless you know how indidual makers tempered their razors or have the rockwell hardness of the finished product available, all you can do is generalise, and when it comes to making a singular purchase basing it on a generality is often disappointing.
