How do you change the blade in a mini hacksaw?

To change the blade in a mini hacksaw, first, ensure the saw is not in use and wear safety gloves. Locate the tensioning mechanism, usually at the handle or end of the frame, and loosen it to release the old blade. Remove the blade by sliding it out of the holder, then insert the new blade, ensuring the teeth face forward. Finally, tighten the tensioning mechanism to secure the blade in place before using the saw.
