I show how to make a small retractable metal saw out of a box cutter and a hacksaw blade. It is very easy to make and requires fairly common materials and tools. It is more portable and convenient then a hacksaw but not as efficient. I used a fairly cheap box cutter so you should be able to get better results with a better quality one. This is a good tool to have when you need to be conservative of space. The hacksaw blade can of course be switched with other blades such as a wood cutting blade or even with some modification of a small file.
It is made by taking out the regular blade in a utility knife and cutting a hacksaw blade to the length of the original blade. The hole that would attach the hack saw blade to a saw is used to hold the blade in the box cutter like the original blade. Now you should be able to extend and retract the hack saw blade in the box cutter/utility knife.
The term "utility knife" includes small folding or retractable-blade knives suited for use in the modern workplace or in the construction industry.
