What is normally the state for named "tool steel" as for example Starret tool steel . Is it saled in soft State ?

Thanks a lot

I would say it’s usually annealed or soft. Got a link for that Serge? Welcome.
 
It looks to me like it is in the annealed state (which is what one would expect).

I wonder if its an odd (small) cross section size? Am I reading that right 5/32 x 5/32 square section x length?
Lots of other 5/32 in wider widths at lower cost

Anyways, yes, tool steel can be substantially more expensive than most regular grades of steel. It has to do with careful control of carbon% & other alloy ingredients necessary to achieve resultant hardness & properties. As a general rule you can only surface harden mild steels with specific processes or only achieve a lower through hardness with specific alloys like 4xxx. So you would only choose tool steel if you want the hardness.
