Straighten a Bent Recipe or Jigsaw Blade in Seconds
Circular saw blades bend quite a bit, but they cannot handle the bending before bending. Avoid straightening them with your hands, as you can burn or cut yourself, and the pliers can leave a kink in the blade where you try to bend it again.
To straighten, lay the blade flat on a 2×4 crowbar with an upward bend. Hit the blade several times with a hammer to smooth out the bend. Be careful not to touch the teeth on the blade as this could damage them. Watch the video above to find out more.
