ive just discovered the benchmade 535 and it really has me horned up. best pocket knife ive carried in terms of ergos, weight, utility. still getting used to S30V, the spyderco sharpener doesnt seem to phase it.
I have several Benchmade knives, and several have the same S30V steel as yours (and presumably the same heat treat). Holds an edge a LONG time - harder than woodpecker lips but doesn't chip.
I think you need to use diamonds to sharpen that blade, as I found.
If you otherwise like the system, you can get diamond rods for that Spyderco.
