Hey There, greetings from the Colorado mountains!! Just joined and am unexpectedly, thoroughly entertained. I'm somewhat new to this craft and just bought a great set of older edgers off ebay and they need sharpening/stropping. Started poking around and came across this thread. What a great idea with the hacksaw, string and chrome paste Badger. Thanks, I'm gonna give it a try today. One question, is is necessary to vary the size of the string for the size of the edger?
