Quote: Push the blade through a piece of standard copy paper. Hold the paper, let the free end float (not held on both sides) and if the blade is screaming sharp and at or under 30°, it'll slice into the paper easily. If it's not that sharp, it might do it skewed or dragged through the paper. It might not cut it easily at all.
That's exactly what I do with ANY edge..even my pocketknives...it isn't scientific, but if your blade will do it, it's about as sharp as you're liable to get it no matter what method you use...and I make sure all my blades will do it...only exception is, I start the cut from the edge of the paper and dont "stab" through it first.
