rat-tail file

The rat-tail file he was carrying was driven into his side, making a wound from which he died in two hours.

It was laconic, but it sounded like a rat-tail file on steel.

It is filed out with a rat-tail file until it is large enough to admit the tube very tightly.

These consist in lateral cuts having a depth of an eighth of an inch and are best made with a rat tail file.

The round or rat tail file is necessary in filing out small holes, the half round for finishing the interior of large ones.
