I have a brand new CRKT M21. I can't seem to get it shave sharp no matter what I do. Now it is sharp, just not razor sharp. I am using the 25* angle which seemed to be the correct one. Is that a bad angle to get razor sharp should I go shallower! It is an EDC to cut strapping rope and the like.
TIA

I cut my angle with a coarse stone and follow with a diamond fine.  My final stone is a sapphire white.  Doing that gets me razor sharp with no problem.  

I strop on a old belt impressed with black polishing compound.

Make sure the rod  and rock is flat.


Glass woks perfect.

I am having a hard time picking the correct angle. What is the trick?
I have also read about a micro grind. Any thoughts on that?
From what I have read, create bevel at a 20* angle then sharpen at a steeper angle like 25*.
Thanks!

Go shallower.

25* is for chopping stuff, but you might have to go in steps with coarser grits first and transition to a more medium grit and less steep angle.
