I got mine today. The edge is shaving sharp. Every Busse, Swamp Rat and now Scrap Yard knive I have purchased has come that way. My Battle Rat was scary sharp.
I should note that I may be a little spoiled. I've spent the majority of my time and money over the years on Spyderco blades, some of which have come so insanely sharp. I've owned eight Busse/SRKW/SYKW blades total, and only one came what I consider truly sharp, ad that was a Howling Rat. All the others had edges so thick they couldn't be sharpened on a sharpmaker without reprofiling. Still most of them came shaving, only one or two dull. I just like to be able to lay my blades across the SM to touch them up. All my blades havr since been reprofiled.
I have handled a Basic with the Asymmetrical edge, and it was incredible. I'd kill for a Basic 9 in Asym edge. That would be the king chopper.
Also, Busse will reprofile edged for free. Had it done many time, and they do a fantastic job.
While I share your admiration for the Basic series fine edge, the Niner is actually a little weak on the chopper scale due to its relatively neutral balance compared to the Battle Mistresses.
