An angle indicating instrument which, used in conjunction with a sliding T-Bevel, can indicate to users what miter saw setting to use when cutting two pieces of material for a miter joint, or for cutting one piece of material requiring a miter cut.

A carpenter tool including a body having a first edge and a second edge, a bubble level carried in the body, the bubble level having a tubular sidewall terminating at opposed first and second closed ends. The tubular sidewall has a first section and a second section, wherein at least one of the first and second sections is parallel to at least one of the first and second edges. The first and second sections are oriented normally with respect to each other. The first and second sections are joined to each other in fluid communication and partially filled with a fluid and a bubble in the fluid, such that the bubble is enabled to move between the first and second sections freely.

Disclosed is a stair tread template ruler, including a main ruler body, and two side ruler bodies. Either of the side ruler bodies is provided with a sliding member that can slide in a reciprocating manner, and the main ruler body is hingedly connected to the sliding members. The two side ruler bodies are arranged at both ends of the main ruler body, and the main ruler body and the two side ruler bodies cooperate to contour a space such as a staircase. The two side ruler bodies are connected to the main ruler body, the sliding members can slide to meet various use requirements, and the main ruler body is rotatably connected to the sliding members, which facilitates adjustment of a relative angle, meets user needs, and simplifies folding and storage. The main ruler body has a multi-segment structure, and each segment is slidably connected to another.

A birdsmouth jig includes a base having an inside edge, a square having a first leg with a first outside edge and a second leg with a second outside edge meeting at and defining a corner, wherein the square is mounted to the base for sliding movement along the base.
