If your wood is showing signs of burning or splintering as it moves through the saw, you probably need to sharpen your blade.
In this restoration project, I revive a cherished pruning saw that belonged to my father-in-law, carrying memories from the 1960s. The saw was heavily worn, with a rusty blade and a damaged handle.
For about the same price as the home decor I was looking to buy, I purchased a tool that would allow me to make as many articulated hanging figures as I wanted.
