How about a round rod for sharpening steep inside curves?
Roger, I got an Edge-Pro Apex model with stone upgrade kit to have all the stone grits. I picked it up from Ben Dale, owner of E-P and one of the very best online vendors I've ever dealt with. He's super-responsive to questions on his product, whether via email or phone. I liked the Apex + upgrade combo so much that I later got a spare one when it showed up on the For Sale forum here on BFC.
Supposedly, if you take the little brass spacer sleeve off the Edge-Pro a ceramic rod from a Spyderco Sharpmaker can be clamped into the E-P and used for recurves or serrated blades. The spacer sleeve is the one between the round handle knob and the sliding aluminum block at the end of the sliding arm. You could likewise mount a round ceramic rod in the E-P and use that on recurves.
For round rod, I recommend getting the 11-inch ceramic rods that Smokey Mountain Knife Works puts on sale periodically for $0.99 each. The wooden handle on them is not glued on very well. I've had them fall off with a gentle bump. (I dropped it on the floor.

) So take the handle off, then score/break the rod to a length to fit the E-P (with or without the spacer sleeve).
FWIW, the coarsest water stone is the stone I use most (reprofiling edges thinner), so I got a couple spares from Ben in that grit. It's also the stone that seems easiest to "dish out" and lose its flatness. A friend said that for hogging metal in a hurry on his E-P, he mounts a coarse diamond-coated steel plate sharpener to the metal blank that E-P uses for their Polishing Tapes. He uses double-sided tape to mount the diamond plate to the metal blank. That allows him to remove the plate when he wants.
