I think your right, i took it out of the device after 600 grit and it cut really aggressively, i liked it alot but continued because ive never had a mirror edge knife before. I may change it back next time around. I went 17 degrees each side with a 16 degree micro bevel with ceramic then stropped it at 17 with 5 and 3.5 micron paste. Im pretty proud of it, i just got the sharpener and only did one knife before i thought i was ready to throw the sebenza in there. These phone pics make me wish i hadnt traded my slr for knives...
