From what I can gather, C11 is a Delica 4. P is plain edge, S is Spyderedge, PS is combo edge. F is flat ground. No letter before the edge grind is hollow grind. BK, BL, GR, etc are standard color codes. No color code is stainless. Not sure what titanium and G10 would be.
The Wharncliffe one I want is something like C11FPWCBK.
This lacks the F and has a 3 character color code (granted it‘s a special colored scale), but the code on my box does include a blade grind, despite no serrated option in ZDP-189, so outside of the VG10 models, it looks like it gets a little sketchy in the coding.
