I admit, I'm a sucker for any new shiny object that catches my eye. Also while I do almost all my sharpening freehand there are some irons where a jig could help. One is a pig sticker mortice chisel because the iron has a shape that is difficult to hold square and most are narrow. Anyway that's my story and I'm sticking to it. Bottom line I ordered the new Lie-Nielsen honing guide with the mortice chisel attachment a couple of days ago, it should be here sometime next week.
Once in hand I'll post if it does what I hope it will do, keep the iron square with out too much monkey motion.
