Antique carpenter's tool (marking gauge), a sumi-tsubo (ink pot). The material is wood, and it has a spool for the thread, allowing it to be wound. However, it lacks a handle, so you have to manually turn the winding part to retract the thread. It's not practical for use, and is more suited for interior decoration or display. ❈The area for holding the ink is dirty, and there is some ink on the thread. In terms of design, a turtle and crane are carved on it, perhaps symbolizing good luck? As it is an old item, there are inevitable signs of aging such as dirt and scratches. Please examine the photos, make your own judgment, and purchase only if you understand and accept its condition. ❈Instant purchase is welcome.
