Japanese Hand made Checkering Files

Specially custom-ordered from a master craftsman, this is a hand-cut checkering file.

Because the artisan is elderly and has stated they may not be able to continue production much longer, this is a rare item that could discontinue at any time.

Pitch: No.5(1mm); No.7(1.5mm) ; No.8(1mm) ; No.9(2mm) 

Working Dimensions: No.5( L155 × T6 × W13 mm); No.7( L155 × T4 × W13 mm); No.5( L155 × T6 × W14mm);  No.5( L155 × T4 × W13 mm); 

Additional Information:  These hand-cut files come from a tool collector based in the Tokyo area. Among them, No. 7 and No. 9 were crafted by the master Edo-file maker, Fukasawa Toshio (深澤敏夫，the third-generation). His family has been hand-making files since the Meiji era, spanning a legacy of 140 years. Born on October 3, 1941 (Showa 16), Mr. Fukasawa retired a few years ago around 2018.
