- See Ken Schwartz's original Facebook post describing this long-cut format.
- Ken Schwartz demonstrates a full-sized Tajima stone and its place in a natural sharpening progression in this YouTube video.
- These flatten easily to a fine finish using an Atoma 140 plate, per Ken's own description.
- Tajima stones are documented as increasingly scarce, with the source mine reported closed for decades.
