So! Despite all the advice on here to the contrary, I went ahead and got a DMT Duosharp coarse/fine 10" stone (as opposed to an Edgero or paper wheels, etc.). I've sharpened an Opinel and a couple swiss army knives to shaving sharp and will be practicing on some other knives in the days and weeks to come.

Any good suggestions for how to figure-out an edge angle? When I become more proficient with the stone, I would like to take some of my larger Busse knives down to a 30-degree edge (15-degrees per side). The instructions say that 2 quarters stacked under the spine as the edge rests on the stone will approximate a 20-degree angle.

Any handy tricks from you pros on how to get a 15-degree angle? Short of using a protractor or measuring instruments because, really, who has the time?

Thanks! :thumbup:
 
Or fold up a piece of paper twice - that angle is 22.5 degrees. Eyeball it from there.
 
I prefer to finish off most of my knives with a convex edge but will also use a variety of stones to reset the edge of a knife I'm unhappy with. I find hand-sharpening knives to be very therapeutic (beats basket weaving) - especially when I'm visualising someone who's been a PITA ;)

Practice with knives you are willing to sacrifice until you get it right. Knives with Scandi grinds (like Mora) are good to start with because their wide bevels help with maintaining the angle. Thin blades with narrow bevels take a bit more skill and patience

the duosharps are the discontinuous surface models of perforated plates over a plastic block, diasharps are generally recommended over them.
