Sorry Griffon I got off topic. Hopefully this will be more helpful. The 3 on the bottom have replacable blades. the 3 on top have to be sharpened. The wooden handles on the Japanese saws are not original, they usually come with handles like the one on the bottom. The timber saw on top is very agressive, too much for dry hardwoods. Tom

The saws are from top to bottom,
1. Japanese timber saw, 420mm,7-4 tpi.
2. Stanley Shark-tooth, 26" 8 tpi.
3. Japanese Ryoba saw, 300mm 9 tpi. crosscut/ 5tpi rip.
4. Japanese Ryoba saw, 270mm
5. Tajima folding G-saw, 240mm
6. Japanese Kataba saw (fine teeth) 240mm
