I wanted to get a Norton set and start practice honing some of my junk razors. When I got the box I new there was trouble as the box was damaged. Sure enough the 4000 side of the 4k/8k stone has some edge damage and the 220 side of the 220/1k side has some edge damage. They offered a 70.00 refund if I keep em, but I wondered if it would affect things down the road. 80.00 out the door is pretty good, but wondered. Would appreciate advice from you experience honemasters.
