DSR7F(Daido) - Tool steel, according to specification, used for high hardness cutting parts. Official composition only lists C and Cr, but also indicates unspecified free cutting element, whatever that means, being in the composition. Based on composition, nothing really exciting, if you trust your maker or brand and they tell you it is good for whatever you need your knife you might go with it, otherwise I'd pick something that has well documented composition and performance reports.
