old piece of steel Warplis - over 35 years old - door stop or knife blank

[4damascus]

I know at a much younger age I picked up this piece of steel as a knife project.
Steel is lableled Warplis. Warplis has similar steel composition of O-1 steel with the added ingredient of Silicone.
I have ground on it a little bit, but there is still a lot of steel there. It is 14" x 2" x 1/4".
I figure one day I will be practicing my stock removal on it and wonder how this stuff hardens. The hardening chart is on there, so I am not asking how to harden, more of does anyone have experience with the steel as a knife and is it good knife steel?
The chart does show it being versital.
It just looks like the steel components varied more than today's steels.
Carbon .85 - .95
Manganese 1.00 - 1.25
Silicone .15-.35
Cromium .40 - .60
Tungsten .40 - .60
Vandium .15 - .25


TIA

Silicon is an element added to steel , silicone is a compound containing silicon as in silicone rubber. O-1 also has silicon , about .25 %.
Warplis has all the ingredients to make an excellent knife steel . With that sizeyou could make a good chopper.
