Anyone use the zetsaw "universal" blades?
Zetsaw has a selection of "universal" blades designed to cut rip, cross, and diagonal all in one blade. They are usually marked III or VIII (not always though) and are usually in the bigger sizes (250mm and longer).
What purpose do these blades serve?
I've used them and they are worse than crosscut saws for crosscut and diagonal cuts, and worse than rip saws for rip cuts... Their kerf/set is very wide it seems and it's really hard to follow a line.
They are clearly not meant for finer work since they don't come in smaller size (with finer teeth).
If it is aimed at DIYers who only want one saw, then a Ryoba (which should be a familiar tool in Japan) seems to make infinitely more sense.
However I have seen videos of serious professional carpenters in Japan with these saws.
Any ideas?
