When to maintainance back side of holly wood shrubbery
blade met knot and roll recurred again
first I made wounded edge scratching to the trunk of the tree
second I filed edge with Leatherman Charge TTi (unnecessary?)
third I clamped the rolled part of the edge with pryor
and tried to bent (usually slipped and edge scratched)
but after that roll remains still
fourth tried to made jig to correct edge
but it didn't work because its groove was thick
finally I hammered both sides of the blade
blade didn't bend and edge didn't chip
and took Sharpmaker (mediam stone), and #2000 sandpaper
waves didn't disappear but temporary repair was possible
