Cutting Box

In my post yesterday about a runaway slave advertisement, I inquired what type of instrument a cutting box might have been. After doing some searching online, I think I finally have an answer - and I can see how someone could get their hand or fingers caught in it and do some serious damage, as the advertisement mentioned about the runaway slave.

The idea behind the utility of this implement is to feed fodder (usually corn stalks) through one end of the trough-like three-sided box. At the end of the box a sharp blade is attached that the operator raises and lowers, thus cutting the fodder into sizable portions that farm animals can then safely consume.

Here is a video of a cutting box in operation. History mystery solved!
