Positionable block assemblies are described. Example block assemblies include a block body with a tooth surface and a plate member with a tooth surface. The tooth surfaces of the plate member and the block body are engageable to interlock the plate member with the block body. Further, the block body is engageable with the plate member at multiple different positions to enable precise positioning of a positionable block assembly to achieve a variety of different working scenarios.

The present invention relates to a novel adjustable sawhorse or workpiece support. The device is an adjustable apparatus to assist in various carpentry and other projects. The device has a work surface, four legs, and a gear and crank mechanism to allow for height adjustment. The device also includes hinges or pivots beneath the work surface that allow for angular adjustment of the work surface. Further, the device has a fastener to secure the work surface and allow for easy removal or replacement, if necessary.

A multipurpose cutter table comprises a table member having a long hole in which a saw blade is installed; a pair of leg members foldably installed on a bottom surface of the table member and supporting the table member; a pair of side supporting members installed to be adjustable in length on both sides of the table member and to support a cutting object on both sides of the table member; and an upper surface supporting member foldably installed on an upper surface of the table member and installed so that the cutting object is placed on the upper surface of the table member. Accordingly, a cutting object longer than the table member can be stably placed by the side supporting member, the height of the horizontal fixed frame can be freely adjusted, and a huge working space placing a cutting object before and after cutting can be obtained.

A system suitable for use as a portable tradesperson workstation is presented. The system includes a main table configured to support and connect with a material working apparatus, the main table positionable on top of and connected to associated adjustable support legs. The system also includes two center adjustment brackets positionable on top of and connected to opposite ends of the main table. Additionally, the system includes a preparation area extension, with associated adjustable support legs, connected to the main table with one of the center adjustment brackets on a top left-hand side of the main table. Further, the system includes a post product working area extension, with associated adjustable support legs, connected to the main table with the other center adjustment bracket on a top right-hand side of the main table. The system is configured to form an assembly and configured for transportation as a portable tradesperson workstation.
