as scalpels, forceps, artery forceps, directors, scissors, etc.--the
surgery of the foot demands instruments specially adapted for dealing with
the horn.

A great deal will depend upon the operator as to whether these are few or
many. The average man of resource will deem a smith's rasp and one or two
strong drawing-knives amply sufficient, and on no account should they be
omitted from the list of those ready to hand.

The ordinary smith's drawing-knife (Fig. 45) is well known to almost
everyone, and is well suited for much of the rougher part of the work.
The careful following up of pricks, however, and some of the more special
operations demanding removal of portions of the lateral cartilages call for

are to be found in the so-called sage-knife, and the modern (French)
pattern of drawing-knife.

The modern drawing-knife differs from the smith's instrument in being

(Fig. 46, _a, b_), and the blades flat, curved on the flat, or curved at an
angle with the edges of the haft.

The sage-knife, as its name indicates, is a knife with a lanceolate-shaped
blade. These also may be obtained in varying forms and sizes (Fig. 46, _c,
