i used to collect BM's and have had i bet a dozen AFCK's, mini's, M2's, prototypes, pre-pros,axis, etc and they are good knives no doubt, the only con imho is a lot were tip down carry which i dont care for, i remember when they 1st disco'd them NGK had 800's for IIRC $59.99(maybe $69.99, one of the 2) which was a helluva lotta knife for the money, i bought 3 and gave them to buds for x-mas and all 3 are still going strong AFAIK.
imho the axis AFCK is still one of the top knives around and is still my fav BM by far.
i still have a M2, an axis prototype and a 800S all LNIB and have a user 800S.
a store in my area had a 800S for IIRC $99 a few weeks ago i started to grab it but hey i already have 2 lol.
