Sharpening Ontario SP-53

[fxsniper]

What kind of edge is on the Ontario Bolo SP-53? Convex? What´s a good and simple way to sharpen?

Looks like a V grind to me, but you could convex it if you want. Some wet/dry sandpaper of varying grits on a mouse pad, using a stropping motion is simple and works well for convexing.
