Sharpening

>>1040904
It is not a choice but a product of the preferred way of sharpening, if you sharpen by hand using stones or whatever, which is the method of producing the sharpest edge the quickest, the natural motions of the hand produces a naturally convex bevel as a by product, not really by choice.

Convex bevel all the way.
Not only is it faster and easier to sharpen that way, but I also found it makes it easier to gouge out huge chunks of wood with it when you need to.

Concave bevel

Thats a secondary bevel in the picture.
A micro bevel is too small to be seen by the eye.

How does the convex even work when the bevel side is pointed towards the work piece (like on a number four smoother) i could understand maybe low angles... But for most.. Just no.

I use just the chisel grind. Because I just use sand paper, a flat piece of granite and a little jig that rolls on wheels. Normally I do 28 degree angle too.

I use MDF wheel on a bench grinder with some buffing compound.

Takes 2 mins, works a treat, better than I've ever been able to do with stones, as I'm shit at things.

Flat or convex.

I find flat to be more controllable when using a hammer (mortise, dovetail, box joint, etc), and convex to be better when doing shapes by hand. If you can't have two sets of chisels, sharpen it for whichever task you use most often.

Compound bevel is for metal/masonry, has no place in woodwork imo. I need that fine edge.

I put a convex on my knives with my Ken Onion Worksharp belt sander (great tool) then refine with my leather paddle strops loaded with 10, 5, and 1 micron diamond lapidary compounds. In practice I only have to belt sand once, then my strops maintain and keep the knife in a perpetual state of razor sharpness. Then the belt comes out again if I get a new knife, or when my roommate uses my Shuns on porcelain plates. I can't train him to stop doing this.

I'm a fan of the Paul Sellers method which usually ends up creating convex bevel. I don't believe it really matters all that much though.
