In addition to its main purpose, hacksaw blades for metal can be used in other ways. Moreover, in this use case they will be no less useful. So if you have broken or dull canvases lying around, you can find a worthy use for them.
1. Spatula for spreading wood glue
A hacksaw blade allows you to very thinly and evenly distribute wood glue over the planes to be glued, like a comb. It is better than a paint spatula or brush, as it allows you to do it quickly and evenly, leaving exactly as much glue as needed.
2. Kitchen knife
An old worn blade can be sharpened and a handle can be placed on it.
The result is an excellent kitchen knife. It is thin, so it cuts with minimal resistance, but it also does not bend, since the metal is elastic.
3. File for the mounting knife
A shortened blade with a widened hole can be installed in a mounting knife instead of a blade.
The result is a foldable pocket file.To ensure that it cuts well, it is better to use a new blade.
