I am trying to hone a Beau Brummel wedge I got off ebay a while back. Just did 50 laps on a freshly lapped norton 4k and it is sharper than when I started and I can make it cut hair on my arm but it sure doesn't want too. I'm wondering if maybe I ought to drop down to a 1k for a few laps? What do you think? How sharp should the edge be after 50 laps on the 4k? The edge is not rusted or chipped and black marker on the spine and edge didn't show any warping. Thanks in advance for any advice.
