FEATURES:

An easy-to-use saw with replaceable blades.
The frame is less likely to interfere even when
cutting curves or hollowing out the inside of wood.
No special tools (wrenches or screwdrivers) are required
to replace the blade. Just rotate the handle to remove
the blade and replace it with a new blade.
All of the blades are completely hardened and tempered,
so they have a long durable, excellent sharpness.
