I posted a thread yesterday on the topic of uneven bevels resulting from uneven grinds on certain knives. I've noticed as of late that there seems to be a technique of blending bevels (blending the secondary bevel into the body of the knife and/or the primary into the secondary). I'm not really sure if this is being created by either a chromium oxided of some sort or a finishing stone. I like the effect as it eliminates the imperfections of an uneven grind on the bevel. Any ideas? Thx.
