Well it's that time and I honestly dont think I have the tools for this recurve style blade. I have a few flate rectangular DMT diamond stones and a couple 53cent ceramic rods and a chef-style sharpening steel. I hate to think I have to invest in a sharpmaker in order to get this done. Maybe a cylindrical diamond rod? Are there really any good ones though? I didnt see any from DMT on the market.
 
I have never let a recurve get so dull or damaged that it needs reprofiling so I just use a ceramic stick or the edges of a Sharpmaker. My plan if I ever need to reprofile is to use "sticky backed" sandpaper on a wooden dowel. You could put some mouse pad material underneath the sandpaper if you want to get sneaky and do it convex.

Hewlett diamond sharpeners seem cool but I've never used one.
 
I used a sharpmaker on mine and it worked great. I just had to reprofile the right side of the front of the blade. Everything else was good at 40 degrees. I highly reccommend you get a sharpmaker now. It will get your knives amazingly sharp, and is very easy to use.
 
Perhaps I best just give in and tell the wife where she can get me a Sharpmaker for Xmas. :) In the meantime I will try the ceramic rod again. The knife definately does not need reprofiling, it just won't sahve the hair on the back of my arm anymore :). I just haven't had much luck with the ceramic rod. I imagine that is due to my technique though because I'm used to sharpening with flate rectangular stones and the ceramic rod seems to require a completely different technique.
 
If your ceramic rod is very fine, you may not be removing enough material to reprofile, especially if its a harder steel, like BM does with their S30V. I have used the diamond "file" that came with my Microtech Scarab. It is quite narrow, so is about as effective as a rod, and it removes a bit more material, making sharpening easier. I just finish off the edge with a rougher ceramic, then smooth ceramic rod. Gets the blade to shaving sharp.

A diamond rod might be just what you need, and can be bought at Wal-Mart for around $5-$7.

Just a suggestion... Grab a set of fine jewelers files and use the rat tail or convex file to get the bevel and the the rods to finish.
