Another thumbs up for the Edge Pro System, Ben Dale is the greatest person to deal with, his system kicks a**.
With that said, I love my Apex, but I really only use it on knives I want really sharp, or to fix bad knives, 90% of my work is done freehand, once I set up the Apex I usually sharpen everything within reach, then that'll last me for a long time, all the touch up's done with natural stones, diamonds or strops.
