Back when the Micra came out, Leatherman freely admitted that the only reason for the chisel grind was for cost savings (it helped to offer a high quality steel tool, at a low price).
The cool thing is that you don't have to re-profile the edge all at once, you can let it happen naturally each time you sharpen it. Just sharpen the bevel side normally, and instead of smoothing the slightly rolled edge on the flat slide, sharpen it at the same angle just until you have a good edge. (This, of course, is assuming that the ascetics of uneven bevels don't bother you...)
