If anyone wants to know what it sounds like to hit a piece of grit in the hone, just watch Lynn's honing video. I'm absolutely positively certainly not saying he had a piece of grit in his hone, but the sound is the same as in his video. If you go to the 3:00 point in the video and listen closely, every stroke on the 4K side that is away from him has a little "snick" sound midway through the stroke.
