Assuming that Barry’s customer does indeed want the sort of curve shown in Marc’s link, that’s going to be a lot of steel to be removed. I don’t think it’s practical to tackle this entirely with any sort of hand operation. I would grind the curve on a belt sander – the Harbor Freight 1 X 30 would do the job. Grind the new profile perpendicular to the blade, then use the belt sander to create the initial bevel(s). When the bevel is established, switch to diamond stones.
Depending on the width (not the thickness) of the cleaver, it may be too high for the WEPS. A possible work-around might be to mount a very long 1/4″ rod hinged to a floor plate, with the cleaver mounted in a vise. Either a machinist’s or woodworker’s vise would work. Clamp the handle in the vise with the blade cantilevered out where the stones can reach it. Here’s an example of one man’s creativity:
I bought a Chicago Cutlery cleaver a few years ago, just for the experience. I sharpened it with a chisel profile (beveled on one side only) and it is an excellent tool for cutting veggies and stuff. Best part is that it will cut extremely thin slices with ease.
