Latest Patents

Kohno's recent patent includes a tubular writing tip that features an outer reduced diameter portion. This ingenious writing instrument consists of a writing nib with a functional writing tip at one end and an enlarged head portion at the opposite end. A resilient seat urges the head of the nib towards the tip of the instrument. This innovative design allows the nib to be movably secured in a nib holder body, enabling it to retract backward against the seat's resilient force when writing pressure is applied.
