Sharpening: Primary/Secondary Bevel

Been using a Edge Pro Apex sharpener for many years.

For my EDC (10yr old Emerson CQC7A, use it every day) in the past sharpened its V-grind at a single angle.

Took the advice of a good friend who has been sharpening for as long time and tried a primary/secondary bevel.

Changed the angle grind on my EDC to a combined angle of 30 degrees. Started with a 220 stone, 320, 600. Just about a mirror finish. Changed to a 40 degree angle, took about 10 very light alternating passes on each side, just the weight of the stone/rod with a 1000 grit stone. Wicked sharp.

Also changed our kitchen knives. 20 primary, 30 degree secondary. Except primary angle use 220 and 320 grit, secondary 600.

Found it takes just a few light passes with the 1000 grit stone to touch up my EDC.

There will be a time when when the secondary will become too blunt, then re-grind the 1st angle and start again.

If you guys haven't tried this method, give a try. I won't go back to a single angle grind.
