First, find out if it is stainless or carbon steel ( pull saws don't have carbide teeth). You can sand a piece and put in FC to see how fast it darkens. Carbon will turn dark almost immediately. Then do a test HT on a piece by heating to 1500F for 5 minutes and quenching in your best oil. If it hardens, it is carbon steel.
Pair it with O-1 for a good contrast. 1080 and 1095 are too similar to W2 to get much contrast.
