the most common cause is a dull blade, resharpening / replacing the blade should solve this.
Remove the blade. With a med file, slide the file on the blade side from the center to outside until it is smooth. Then sharpen other side from center out. Place the blade on a balancing cone, file the heavy side until it balances on the cone.
On a blade, the cutting edge is the sharp side.

Shearing requires one blade to pass over another blade or a fixed edge. Cutting only requires one blade.

the wood blade has sharp long teeth and the metal on has small tiny teeth
The cutting blade on a sawmill is typically powered by an electric motor or a gasoline/diesel engine. These power sources provide the necessary energy to drive the blade through the wood to perform the cutting operation.

The Hit Tools Turbo Rim Diamond Saw Blade is good for Cutting Granite.
It's a saw for cutting materials, it has a vertical blade and a motor moves the blade up and down cutting through materials, it is able to make very tight turns when cutting.
Aside from being sharp, the blade shape of a katana supports a good cut. The profile of the blade is that it is convex, and this moves material being cut out and away from the edge of the instrument. Picture the knife as a wedge, but one where the sides are not flat. Rather, they sides are "rounded out" instead of being flat or concave. This helps explain why the blade of the katana is so good at cutting.
