Rasp.
It's called a cutlass... don;t know exactly what you're asking, but this is what I came up with.
On woodworking saws the teeth are alternatingly offset slightly to left and right. The amount they are offset needs to be the same amount to ensure a good clean cut. This tool is used to do that. It bends the teeth to the correct amount and ensures the offset is the same along the length of the blade.
A scythe is a long slightly curved blade which is fastened to a handle at an angle. This tool is usually used for agricultural purposes such as cutting down grass, weeds or grain by hand.
To answer that, I'd have to know what the heck you're talking about. Do you mean making your hand into an airplane shape? using a non-mechanical plane (wood-shaping tool) to make "the best shape", whatever that would be? something in geometry? As put, this question is totally meaningless.
The type of tool you might be referring to is called an "Adz".It's an axe-like tool where the blade is at a right angle to the handle, the blade is curved for shaping wood.
You have to use a hatchet for woodcutting.
Adz: A woodworking tool; A tool similar to an ax, with an arched blade set at right angles to the handle.
An adze is a cutting tool with a curved blade set at a right angle to the handle, and used in shaping wood.
"Adds" is a word meaning "sums," and "adze" is an old woodcutting tool.
Adz. It is an axe that has the blade turned 90 degrees so that when it is struck against a piece of wood it chips towards the worked. Then again axe is also a three letter wood shaping tool.
An adze is a hand tool similar to an axe but with the blade oriented perpendicular to the handle. It is used for shaping or smoothing wood, typically in woodworking and carpentry projects.
Three objects pop into my mind: awl (tool used for punching small holes in wood), adz (axlike tool with a curved blade at right angles to the handle used for shaping wood), and axe (for cutting wood) I guess it's adz you're searching for. I think you meant 'shaping' instead of 'shaving'.

A wood shaping tool that is three letters could be: - Adz - Awl - Axe - Saw
There are many multi-tools on the market that do have a small saw blade on them.
That is the part of a bit or blade that fits into the receptacle on the tool
