What kind of saw makes curved cuts in plywood?

What type of saw is designed for more heavy duty jobs than the jigsaw?
Also known as a sabre saw, reciprocating power saws are designed for heavier duty tasks than jigsaws and utilize an oscillating cutting action for more aggressive cutting. You use a reciprocating saw with both hands, meaning it’s far easier to cut overhead or vertically than with most other power saws.
Which saw cuts with a push and pull motion and is used primarily for roughing in work?

What is a tooth saw used for?

What is a friction folding knife?
Friction folding knives are the original folding pocket knife. Before the invention of slipjoint and locking knives, all folding knives used the friction of the blade tang against the handle and the pressure of your hand to stay open. The absence of a lock means that these knives are best for light cutting tasks.
What is a slip joint knife?
The blades of pocket knives with a slipjoint mechanism are kept open by a spring. These knives feature a classic build and are usually equipped with a back spring. The blade stays open without a lock but can be closed manually once the spring force is overcome.
Who invented folding knife?
The earliest known pocketknives date to at least the early Iron Age. A pocketknife with a bone handle was found at the Hallstatt Culture type site in Austria, dating to around 600–500 BCE. Iberian folding-blade knives made by indigenous artisans and craftsmen and dating to the pre-Roman era have been found in Spain.
