I use a very bright light to examine the edges for damage.
I use 3M fine automotive wet & dry finishing sandpapers on a hard flat surface.
I begin with 800 grit, then 1,000, then 1500 grit paper. Maybe 600 start if there is serious damage to the edge.
I use Chromium Oxide and Aluminum Oxide honing compound on hard, thick paper for finishing.
CrOx is 0.5 micrometer, AlOx is 0.25 micrometer nominal particle sizes. That's good for western red cedar.
