There are a few different ways that you can cut gun case foam, and the method that you use will ultimately depend on the type of material that you are using. If you are using a standard mouse pad, then you can simply use a sharp knife to cut through the foam. However, if you are using something like memory foam, then you will need to be a bit more careful. The best way to cut memory foam is with an electric carving knife or a hot wire foam cutter. These tools will allow you to get a clean, precise cut without damaging the material.
When cutting foam, it is important to always use caution and go slowly. This is especially true when working with memory foam, as it can be easy to damage the material if you are not careful. Always make sure that your cutting tool is sharp and that you are following a straight line when making your cuts.
If you are having trouble cutting through the foam, then you can always try using a higher setting on your hot wire foam cutter or increasing the power on your electric carving knife. Just be sure to go slowly and be careful, as you don’t want to damage the foam. Check video below.
