A knife switch is just a straight piece of copper that looks like a knife.

The cabin at the lake has fuses and knife switches.

I'll bet it has knob and tube wiring as well.

Where I lived in western NY there's still a lot of knob and tube
wiring around. It's safe except that now days, people pile insulation
on it, etc. Add to that that when knob and tube was used, the average
house's electrical devices were one small light per room! So, you
overload it, then pile insulation on top of it, and it overheats.
