Description

B43K covers implements designed for writing, drawing, or marking on surfaces, including pens, pencils, markers, brushes, and related writing instruments. This subclass encompasses the mechanical and structural design of these instruments, such as nib configurations, ink delivery systems, barrel constructions, and grip mechanisms. It includes both traditional writing tools and specialized implements for technical drawing, calligraphy, and artistic applications. Related accessories and components integral to the function of writing or drawing implements are also classified here, though office furniture and broader bureau accessories are covered separately under B43L.
