Any tips for how to hold the knife and the stone? I'm having difficulty hitting the Apex every stroke, and sharpening away from me, I can't see the bevel
With experience you can tell if you're hitting the apex by the sound and feel during the stroke. Catching the apex induces greater drag, while using too acute of an angle has the knife sliding around more.
When I sharpen the presentation side, my right hand basically grips the handle like I would if I were using the knife, while my left index and middle finger rest on the flat of the blade near the tip, with my left thumb on the spine.
When I switch to sharpening the back side, I use more of a pinch style grip with my right hand, left index and middle finger on the spine near the tip, with my left thumb on the flat of the blade.
How you sharpen will influence how you feel about forming and removing burrs.
For example, razorsharps pics shows a wide, highly polished bevel.
In contrast, my knives get the bevel formed on an extra course DMT stone, then I don't touch anything else besides the apex. (Sometimes on knvies with corrosion prone steels I take the bevel to a DMT fine polish).
I'm of the opinion that polishing an entire bevel is a big waste of time. Polish the apex if that's the edge type you want, but polishing steel behind the apex is just for show and has basically zero influence on cutting ability.
I reprofiled and sharpened up some knives last night. My entire procedure involved exactly two sharpening mediums...a DMT XX Coarse bench stone, and a Spyderco medium bench stone.
I form the bevel on the DMT. I eliminate the burr as best I can, expecting shaving sharpness right off that course stone.
From there I grind only the apex on my medium Spyderco ceramics, until it's sharp enough to pop off individual pieces of stubble by merely touching them.
Someone that does not utilize microbevels, or goes through a more complex grit progression, may find more value in intentionally raising a burr.
Likewise, someone that sharpens a knife when it is dull might also find more value in raising a burr on purpose.
If you're like me and you touch up a knife when it stops shaving and utilize microbevels, I think raising a burr is a waste of time and steel. It only takes 4-5 strokes per side to refresh the edge in this case. It'd take longer to deburr than it would to simply use alternating strokes a few times per side.
Like they say, there's more than one way to skin a cat.
