Kanto Retired Carpenter's Saw Metate Tool Set

I purchased these from a retired carpenter in the Kanto region. The "Hasami-ita" (saw-clamping board) is shop-made by the carpenter himself and accompanied him throughout his entire career. While these tools have been well-used, they remain in great condition and are ready for continued use.

Tool set contents (starting from the top of the first photo):

1: Total of 28 files across 5 different sizes, capable of covering the sharpening work for most types of saw teeth.

2: Two wooden handles are included for files. The files are interchangeable.

3: A Japanese steel spine with a wooden handle, designed for securing the thinnest/finest files

4: Small, Medium, and Large Medate Hammers

5: One Hasami-ita (saw-clamping board) with a maximum clamping length of 42cm.
