Yep, it's not a typo. I got some prybars and things from countycomm.com, which they say are made from D-9 tool steel. I can't seem to find anything about this steel easily online, however.

Does anyone have any info/datasheets about this steel, in regards to its composition and HT info?

Thanks!

Are you sure its D-9 ? I have heard of D-7 its similar to S90V with a little less chromium http://www.diehlsteel.com/d7.aspx

The description on their site says 'D-7'

What's SV-90? Haven't heard of that one either..or do you mean S90V?

Yes thats what I mean , little cloudy this morning . I cant find D-9 in any steel charts but, that does not mean that its not made . It just means I have never heard of it . could be something new . If its even close to D-7 it is extremly hard to grind and darn near impossible to handforge. many belts....http://zknives.com/knives/steels/steelchart.php Maybe someone with more steel knowledge could chime in .
