I have a fair number of nib knives in my knife-boxes, and generally carry a clipped Slysz Bowie in rh pocket and my Bradford Guardian 3 in Vanadis 4 Extra in my cross-draw belt. Been using cross-draw for two yrs or so now, and gotta admit it gets most of the use since it's so quick to hand. The Vanadis 4E is hard and shaving edge, from the Bradfords, and stays that way just fine with little or no maintenace. Also have used his 3G's in M390 and 3v, although I don't claim a fondness to N690...
No doubt that I'm a 3...I popped a lid off of a jar a day or two ago with my Bowie, and picked up several nicks in the edge that I can feel with a thumbnail. Time to get that Edge Pro back into action; I really like that thing, and my freehand sharpening kinda sucks.
