[The silent but deadly king]

I want to make necron pyramids, ned to cut edges at 45' angles. Will this tool do it for me?

That tool is designed for cutting foamboard/foamcore. Video at manufacturer's website

 

In fact, it looks like all of the tools from that company are designed for 3/16" (5 mm) foamboard. (website)

 

If you're constructing your Necron pyramids out of foamboard, that tool (and others from that company) will work. If you're constructing your Necron pyramids out of other thicker materials, you might look into a miter box and miter/hobby saw.
