The Shinwa trailing compass is a traditional tracing instrument used to accurately transfer assembly profiles, particularly in the construction of solid wood houses, log structures, or carpentry and joinery work requiring high precision.
It is also known as a carpenter's compass or log builder's compass. Its design allows for a constant opening thanks to an adjustable spring screw, facilitating the repetition of identical lines.

An integrated spirit level helps ensure the tool is perfectly horizontal when drawing, improving overall marking accuracy. The compass comes with a curved steel point for copying and a drawing pencil; both can be mounted on either arm as needed.

The robust mechanics and construction, true to Shinwa's reputation for precision measuring instruments, make this compass a durable and reliable tool for repetitive and demanding layouts.
