I use a simple flat 2 sided diamond coated block.

You can get them for about $17.

heres how you use it.

1. Place block on level stable surface
2. Spray windex on it *windex is an amazing blade lubricant!*
3. hold the knife between 20-30* higher the degree, the more durable the edge will be, but less sharp, lower the degree, sharper but dulls quicker. I would say 25* for a pocket or hunting knife
4.Start with the rough side of the block.
5. In strong but small circular motions, swirl the blade around the surface of the block. until the rough feeling becomes smooth
6. flip the knife over and repeat on the other side.
7.Take the blade at your desired angle, place it on the block and push it away from you in a straight line. Make sure to do this all along the blade to remove the burr.
8. flip the block over to the smooth side.
9. Repeat the process all over again, adding windex as needed for lubrication.

When done your blade should be able to shave paper, or hair with little effort.

I've been doing it this way for a LONG time. Never failed me :-) Even my $10 ozark trail wally world knife is sharper than most SOG's, and BOKER's out of the box :-D

Hope this helps.
