Perhaps instead of referring to it as dulling or killing the edge, I should've called it flattening and preparing the edge for a new bevel set due to micro-chipping. Quickly working out small chips or bad metal (rust, pitting) is the only time I will intentionally dull an edge unless it's on my Gold Dollar that I use for practice and experimentation. Believe me, if I can get away with dropping only as far back as 8k or 4k I'm not going to intentionally dull a blade just ensure that I have to go back to 1k. Honing and bevel setting is fun, but it isn't that much fun.
