Knife edging the crank for those not in the "know" is making the leading edge of the crank counterweights come to a sharp knife-like surface.
I have done this on many engines for drag racing purpose, but usually combined with a "windage tray".
The tray is a piece of metal...usually aluminum cut to the profile of the crank as it revolves.
The tray ends up looking like a bunch of fingers coming from the bottom edge of the crankcase pointing towards the crank.
The whole idea is to strip the oil off of the crankshaft instead of letting it flail around and create oil mist or foaming.
In our case, with the flat six, I doubt it would be easy to do and probably not do anything beneficial.
The knife edge will cause less friction or drag, but also of debatable benefit.
