Steel quality

[Apokrif]

Is there somewhere a review of the various sorts of steel used for SAKs and multitools ? (hardness, resistance to rust...)

 

[frank k]

Victorinox uses a steel equivalent to 425M at 55-56 HRC for the blades and 49-53 for the other tools. The blades are (nickel?) plated so there isn’t much of a problem with rust except perhaps for the edges where of course there is no plating, but the steel itself is fairly rust resistant.

I think that most of the multitool manufacturers use 420 or 420 HC and they are probably no harder than the Victorinoxes. 420 series is also pretty corrosion resistant.
