Not close to HSS, but harder to hone than the razors I've had that were very plain steel.
I think razor are tempered differently to woodworking tools. Could be a factor.

It can be, but some razors are harder tempered than others. There is some overlap, but my experience with old razors (as in century old) that advertise that they're tungsten steel is that they are tempered harder and much harder to get into good shaving shape than a razor that is advertised as being silver steel or "best crucible steel".
One can't assume razor "tungsten steel" and Record "tungsten steel" are the same; both proportion of tungsten, other components (e.g. vanadium ) and subsequent heat treatment might very well vary.
Fundamentally (to use a GBBO analogy), tungsten is an ingredient, not a recipe.
