I used to work with a guy who did a lot of wood lathe work. He was complaining about keeping his tools sharp. I have him a small piece of flat stone, a piece off an old trophy stand, and some thin sheet copper and a tube of 15,000 diamond paste. You use carpet tape and stick down the copper to the stone. Then use a few small dabs of the diamond paste and rub in in with another stone, One with a sort of flat side out ouf your garden will work. Two or three applicaations of the paste and you have a very good flat lap. It is a lot more agressive than an Arkansaaw stone or India stone but gives a finer finish than either. Once the copper is charged, all you will need is a refresh now and then. You can pick up a tube of the diamond at most lapidary shops and some tool supply stores. Getting it on line is easy. For $10 you can get a lifetime supply.

For what it's worth.

by the way, I keep a small pocket hone on my bench for sharpening the knife blades. It's not as good as the above trick, but I had it from my days as a machinest. Used it for touching up lathe bits and such.
