Ok, here's your problem. When dealing with simple carbon steels the heat treat can be messy. If money wasn't a problem a D-series tool steel like D-2 would be excellent. The advantage these give in a production setting is they are air hardening.
Tungsten is an excellent alloy, but too much could make the blade brittle. Moly is a key alloy for the air hardening steels.
Your originally wanted a stronger material, as I stated there is a trade off between strength and edge holding.
Off all the steels I mentioned, L-6 would show a good balance between strength and edge holding. D-2 would roughly double the edge holding but would be more brittle.
