there are basically 3 types of busse edges, standard v convex, blended or zero convex, and asymmetrical. asymmetricals are only used on the basic series and older models (the straight handled line) and aren't really used on current productions. standard v is on everything cg, blended or zero is used on satin finished custom shops, le's and competition finishes. The rules aren't set in stone, any model can have any edge applied to it at the factory if a customer asks for it, but the above describes whats come out of the busse compound over the last decade.
convex: pretty much every busse's edge is done on a slightly slack belt, creating a convex edge. some are rounder than others, but if you've ever used a flat stone on them you'll see that every single edge is convex.
v: most common format
asymmetrical: one side is a wide high convex, the other is a short flat. your supposed to stone/rod sharpen the flat side and strop the convex
blended convex: this is on custom shop and satin models, where there is the standard v convex that has had it's corners knocked off to help it blend better. the difference between the flats of the blade and the edge are still clearly visible.
zero convex: the competition finishes are like this, the gladius looks like it'll have this as well. the main grind goes from full thickness to cutting edge without a clearly discernible secondary edge bevel.
