Very roughly, it was a "cheap version" of AFCK (Benchmade 802).
When I bought my M2 AFCK, I asked to Benchmade why the Ascent was so similar and so cheaper, compared to ATS 34 AFCK too.
They answered they were very similar, but there were some differences, mainly in the handle: in the Ascent it was made by Zytel, in AFCK it was made by titanium and G10.
Moreover, the Ascent was a lockback, while the AFCK is a linerlock.
I still find a description of Ascent at
www.benchmade.com, perhaps they still sell it.
I don't know if there are Ascents in the shops anymore, but you can go for an AFCK (in M2, IMHO).
