A saw-horse (saw-buck, trestle, buck) is a beam with four legs used to support a board or plank for sawing. A pair of sawhorses can support a plank, forming a scaffold. In certain circles, it is also known as a mule and a short sawhorse is known as a pony.
The sawhorse may be designed to fold for storage. A sawhorse with a wide top is particularly useful to support a board for sawing or as a field workbench, and is more useful as a single, but also more difficult to store.
A sawhorse can also be used as the base for a portable work table by placing a sheet of 3/4" plywood or even a door on top of two sawhorses. If the sawhorses are strong enough, the portable table can be used as a platform for tools like a table saw, although with caution if the top is not secured to the sawhorses.
- A sawbuck is a similar device for working with logs and branches.
- Barricades fitted with flashing lights and used to block excavations or road construction or other safety-related purposes. Formerly made of wood, now many have metal structural members or are made wholly of plastic or composite.
- The A-frame barricade or parade barricade resembles a sawhorse with a brightly painted top rail.
- The Type I (or II) barricade also known as a waffle-board barricade resembles a sawhorse that can be folded flat. Type I indicates sheeting on top; Type II has sheeting on top and bottom.
- The Type III barricade has multiple rails supported by two end posts with feet.
A device for crowd control in the 20th century had the shape of a sawhorse made of wood. The legs are similar but rather heavy duty facsimiles of the hobby version of about the same height. The horizontal bar consists of a heavy-duty plank about 4.2 metres (14 feet) long with printed on it in large letters: Police Line - Do Not Cross. Many cities have chosen to replace this wooden barrier with the French barrier, which is a metal crowd control device.
