sintered and powdered is the same animal. the big difference is what is produced. sintered typically refers to a part that is made by filling a mold with powdered metal, compressed with high pressure then heated. out pops a gear or brake drum. CPM makes a big round chunk that is then forged and rolled into sheets or bars.
the only "blade steels" i can think of would be AEB-L/12C26 family which was developed for razor blades, cutlery and other cutting tools and the Hitachi color family although Hitachi only makes a small quantity of these steels.
I have heard S30V was developed for blades but also heard the blades they were talking about were the kind that bulls into bologna. I worked for several years making ceramic catalytic converters, main ingredients were titanium dioxide and ammonia, and i guess the extrusion screws and casing could have been CPM.
M4 tool steel has been around since the 1930's as a wear resistant version of M3 and M2, Crucible makes a CPM version and a conventional version.
plastic dies may be aluminum, but will have tool steel inserts where the plastic is extruded and formed.
