CARPENTERS TREASURE Japanese Black Sumitsubo with reel
Much like the familiar carpenter's chalk system, but the Sumitsubo produces a much finer line. Ink grains are dissolved in water and the cotton wool is soaked in this solution. The line is drawn through the damp wadding, fixed under tension and snapped against the surface - a fine, straight line is produced.
11" long x 4 1/2" wide x 4" tall weighs 1 lb 6 oz.
The sumitsubo is an important spiritual symbol, so the early custom was to leave it in the newly built shrine or temple as a treasure.
This fabulous vintage piece has an unusual blacksmith repair (iron staple) where it began to split. Sumitsubos are carved from one piece of wood. This simple design, with repair, may have belonged to a humble carpenter. This was used, the "pot" has ink residue coating the interior.
Unknown wood /blackened wood Missing Silk Line, Handle, and Karuko (pin tip) I do not know if the wadding is original or correct it came with it The reel may not be original, it is of a different color/wood
