That is a pretty edge, Brian. To slice maple that thin is proof of its sharpness. I just stepped outside again and tried your technique. My fuzz sticks are getting fuzzier and fuzzier. Thanks for the tips. I found that the thick spine actually helps in putting pressure on the back of the blade with my thumbs. Now you have a fun knife. You can baton and chop down small trees with it, too. Unsub recently did his edge the hard way, by hand. I suppose he is doing shaved ice with it by now.
