Fence

Fences are used to keep curious people off your land (and items), or to keep your animals from escaping. A single part of fence requires 6 wooden stakes. Fences can be used as a trap-fence, which blocks the way of animals and guides them straight into a trap, usually a trap pit. The player can climb over them, and some animals also can.

In the "Handcraft Options" menu, opened with command [Shift + M], in the "Traps" menu there is the "Build trap-fence" option, that makes the exact same fence as the "Fence" in the "Building and constructions" menu.
