Although half the hobby from a terrain building perspective is keeping an eye out for discarded toys, boxes and other shapes to build with, the other half is translating an idea into something tangible. The material that would be most useful for this is polystyrene, not the shitty expanded kind (with the little balls that keeping break off even years after sealing painting and pouring holy machine oil on it) but the solid extruded sort. It is reasonable solid, lightweight and with a few easy measures quite durable. One thing it is not, is easy to cut. As with its cousin foam board I keep spare blades at the ready and an average build tends to eat up a full set of spare blades because polystyrene is dull (pro-tip: when given a last request at the guillotine, ask for polystyrene, quickly dull the blade and walk away with a sore neck ;) ).
Add to this problem that it is hard to keep cut edges straight a tool is needed. So a few years back I decided to invest in a hot wire polystyrene cutter. At first I attempted a few 'home-build' projects that all failed and finally I just forked over the cash for a 'real' machine. This is the one.
