Is a chainsaw a wedge

Answer 1

You can use wedges with chainsaws... for example when falling a tree it may be useful to use wedges to help relieve pressure from the saw, or to direct the way the tree is falling.

I wouldn't really consider the chainsaw itself as a wedge it can certainly be squeezed by wood when it settles as one is cutting it.

Thinking of the chain itself... and the blades of saws, or for that matter, kitchen knives. The teeth on the chain are sharpened into somewhat of a wedge shape. I've always thought of it as using an abrasive action, but perhaps one could think of the teeth digging into the wood as tiny fast moving wedges.

Your kitchen knife is usually pushed down through an object, perhaps with a little sawing, but generally with the effect of vertical downward motion.

On the other hand, the chainsaw chain is dragged in a across the object in a horizontal motion.
