I haven't seen anything...but I did snag this from the Rodent 9 posting:

"Our Ultra Convex Bevel is a mere 1 degree off flat, CNC bevel, that rises to within less than 5/16" from the spine." Pair this with the picture of the Rodent 9, and it appears the slightly convex grind that Dan originally spoke of on the 511 may very well be this UCB that is advertised on the Rodent 9. The blade looks to have similar milling lines...or, UCB's.
