A simple hammer you'll sharpen, maybe a bog standard angle grinder. These are the cheap ones, and all you need.

Bigger panes of laminated glass is expensive, but you can start small, no? I'd go to the local glass shops and ask for their scraps, for example.

However, the point is not the cost of the supplies, but supporting the argument by putting out something better than the thing being criticized.
