As well as having all the usual benefits of Japanese saws, the Hassunme saws also feature replaceable blades. Changing the blades could not be easier; gently tap the back of blade on a block of wood until the blade loosens, remove the old blade, insert a new one into the holder and tap the back of the holder on the block to seat the blade. The rip cut saw has a 0.5mm thick blade, 250mm long for effortless ripping of long boards.
