Just curious what you guys do if you want to sharpen your knives to a more extreme or steeper angle. Do you just try for 2dps lower than factory on each side? How do you determine the limits of the steels angle? What is a good test to see if it’ll chip, or roll.
I’m curious on what inclusive angle everyone is using and what knife is it?
I’d like to push both of my knives a little further, if possible.
I sharpen my knives around 10-12 degrees per side, then apply a 15 degree microbevel.
I have never seen a pocket knife show edge damage at these angles regardless of blade steel.
Smaller knives I tend to take a bit thinner.
My favorite test for edge durability is aggressively carving knotty, seasoned hardwood. It will chip or roll the edge if the steel was ground too thin.
If you search through my posts I have some edges ground so thin you'd swear they'd chip if you looked at them funny, but they pass the wood test. They work great on stuff like cardboard and veggies.
Most people never determine how thin their pocket knives can be ground. I have. I've taken multiple blade steels past the point of failure, and studied how and why they failed, to get the angles I chose.
10-12DPS with a microbevel is a little overkill for my uses, but it still cuts extremely well.
I can slice cardboard with my knives until they are completely dull, then touch them up in less than one minute using my medium bench stone.
Typically I only use two stones from start to finish.
I grind a bevel with an extra course DMT diamond plate. I refine the edge as much as I can on this stone to minimize the bur.
From there, I apply the microbevel on my medium Spyderco benchstone. It only takes 5-10 strokes per side. Any more than that is wasting steel.
My edges are sharp enough to whittle individual hairs and pop off arm hairs 1/2" from the skin using this process. No polishing past that, no strops, just set the bevel on the DMT then apply the microbevel on my medium stone.
I could never do the 1 hour + grit progressions some people do. I can think of other ways to spend my time.
