Check what bevel angle the ACCU makes. I had one of those types and realized my blades were VERY sharp, but just one day in the quiver foam and they lost sharpness.
I found out they were set to produce a 19* bevel. Lots of views on this topic, but I don't care for anything less then 25* as it's too fine an edge, gets scalpel sharp, but being to "thin" it wears quickly.
I had evidence it dulled going THRU the deer... Switched to KME...have both the BH sharpener and the knife system...
Ron at KME suggests corrugated cardboard works better then leather strop..leather will mound up like a wave ahead of the edge and roll it over where cardboard doesn't. FWIW...works for me and is way cheap!
