+1 on any finisher, +1 on 12k

Its really up to you. If you know you're gonna want hones, get the 12k. I like the Nani's and am pursuing a full set, but I like natural finishers more. I touch up on anyone of: J-nat, Thury (Escher), or Swaty (Barber hone). It mostly ends up being whatever I finished the blade on (figure it preserves the finish?) or if its a workhorse blade that someone else honed, the Swaty does a great job 5 laps and you're done. I will say that I like the Escher's edge most, seems sharp but very smooth, but not really enough to justify the price. In retrospect, I have trouble justifying a lot of stuff though.
