Well your going to here a lot of diff answers, but what type of grind o you have on the blade. If its a convexed edge then you want to strop it. If not just use a diamond flat stone.
The way i find the angle is i lay the blade on the surface of the stone and tilt the blade until the cutting edge is flat to the stone. THen i make my pass`s on the stones.Keeping the angle consistent. Not a gret way but i can usally get my knives working sharp.
Now for stropping, I just got my Boss Jack and Im in need of some direction there, as to this is my first convexed edge.
