If you’re familiar with backsaws, you know that the brass or steel spine is usually either parallel to the teeth or is slightly closer to the teeth at the toe (front) of the saw than at the heel (rear).

I bought an old saw online recently that is in great condition, except that the spine has slipped slightly so that the spine is slightly further from the teeth at the toe than at the heel. Is there a good way to re-align the spine with the teeth without damaging the teeth or the saw plate? Thanks.

Clamp the saw plate tightly between two full length pieces of wood, then adjust the spine as needed. I have completely removed spines and reinstalled them using this method, no problem.

Ryan, does “adjusting” including tapping the spine in place with a hammer?

Sorry for the delayed response Brett. Yes, I use a hammer, but never metal on metal. I use my wood or rubber mallet, or if you must use a metal hammer, be sure to use a wood block in between. I’ve never damaged a spine.
