How do you sharpen a Hamiguri(sorry if i buthcered the spelling) grind?

[Lil' Temperance]

How would one go about sharpening a hamiguri or appleseed grind as they are also called. I'm a Spyderco nut and I carry a Lil'Temperance and Bill Moran featherweight daily. I'm thinking about picking up a Spyderco Bob Lum Tanto folder an dfixed blade for work and leave the Lil Temperance and featherweight for my non work EDC.
My concern is that the forward edge(tip) is an appleseed grind and I'm a SHlTY sharpener even with a sharpmaker 204. and suggestions short of sending them in for sharpening every time they need it?

There are two main ways to sharpen convex bevels. The first, and easiest, is to use an abrasive which can deform to fit to the curvature of the grind. A slack belt sander will do this, and is what is usually used to make them in the first place. You can also just use a roll of sandpaper as a free hanging strop, or lay the sandpaper on something soft that will give to the shape of the knife. In all cases the blade is sharpened edge trailing.

The other way, is using a small hone, you work it along the bevel matching the curvature by hand. You can also use a large hone and basically and strop the blade, rotating it to match the curvature during the stroke. I find this method with the large stones to be very difficult, however it comes natural to some people.

As in general, the wider the grind, the easier it is to sharpen. Fully convex knives, with no secondary bevels are among the easiest to sharpen freehand, as are puukko style full flat grinds.

I never tried this, but i heard fine sandpaper, an old mouse pad and some glue does the trick
