DMT curved stone?

I've seen several people reccomend the DMT curved stone, but it seems to be discontinued. Is there an effective replacement for it in DMT's product lineup? I know they have a serration sharpening rod, but that hardly seems efficient for large recurves and hawkbills.
 
I'm still seeing DMT's 'diamond cone' sharpener listed on Knifecenter's and Woodcraft's sites. A couple of sizes apparently, 6" and/or 8", in Fine grit (25 micron).

Barring that, you could still use silicon carbide wet/dry sandpaper wrapped around a cylinder (PVC pipe, broom handle, dowel, etc.). It's very cheap, and works well.

Edited to add:
Amazon lists the DMT diamond cone too (also 'In stock').

EZ-lap has a line of diamond oval rods in various lengths and grits, I like the 3/4in width rods for recurves.
 
Oops, I wasn't specific enough. I was thinking specifically about the curved stone for the DMT aligner.
 
The curved aligner hone is not worth the purchase especially if you don't have the aligner. It's small and only comes in one grit.
 
I have the DMT fine grit recurve stone. I wanted them in different grits so I got some coarse flexible stuff they have, carved a piece of wood like the recurve stone and glued the flexi-sharp to it. I used it in the DMT aligner and it worked great. You need to call DMT to get the flexi-sharp in sizes different than what they sell normally.

If you do that you'll find the flexi-sharp is pretty stiff and it could crease when curving it around the wood. I was successful though, but it felt like it would crease at any moment as I bent it around the wood. The curvature of the existing DMT stone is rounder than you actually need unless you have some pretty severe karambit blades so the wood doesn't need to be all that round. As you carve the wood, just get it round enough to stroke inside any recurve blades you have is my recommendation. That'll help when gluing it also because being as stiff as it is you'll need some good glue. Epoxy should work. Make sure however you clamp the flexi-sharp until it sets that it will hold until the glue sets.

I just thought about it but I don't have any recurve blades any more. If I do get one (or more) I have an alternative way to sharpen them. If you would be interested I'd sell the DMT fine grit stone and the one I made if you are interested. The one I made is coarse grit flexi-sharp. It did a very good job of re-profiling one knife of VG-10 I used to have when I used the aligner. If you are interested let me know. If not, good luck at whatever you decide and try.

I was looking for something and found this and thought you may like it.

This looks like a great price for the curved stone and a serrated stone set. I have used both and they work great for the aligner. If you use the serrated sharpener with the aligner you should move the blade along in the clamp keeping the stone at a 90 degree angle with the serrations. That's what I did anyway.
