I re-ground a blade made from this steel and it threw sparks off the belt like I have never seen.So what is in this steel that makes it so "sparky"

1% carbon. It also has 13 1/2% chrome.

The CPM154 I have been using has 1% and 14% chrome and I have not had any sparks follow the belt all the way around and burn my dome like this 19c27.

Interesting. DT-carbon puts out a load of sparks, too.

154 also has 4%moly in it so the spark pattern will be duller. It just means that it has a good heat treatment. Trust me on this one. It may not be 19C27 though.
