No reason why the Spyderco should not work. But I think you may wind up rounding the heel and toe; especially the toe as you leave the rod.I have used spyderco triangle rods on a razor. I don't recall how that worked out. I remember which razor, but I don't remember if it was the final stone used.
I have a razor that needs honing, perhaps I should take one for the team and try the spyderco triangle rods and report back.
