KNIFE-HANDLE.

Specification of Letters Patent.

Patented Mar. 13, 1917.

Application filed September 11, 1916. Serial No. 119,525.

To all whom it may concern Be 1t known that I, DANIEL J. LEFEBVRE, a sub ect of the King of England, residing at East Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Knife- Handles, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to cutting tools and particularly to handles for knives, the invention being particularly adapted for use with knives for cutting leather.

The general object of the invention is to provide a knife handle so constructed that a firm grip may be secured on the knife handle, the handle being so formed that when properly grasped the knife will be held in a predetermined position, and further, the handle being so formed that there will be no danger of the operator cutting himself.

A further object is to so form the handle that it will not blister the hands and the work may be done with a maximum of ease.

The invention is illustrated in the accompanying drawings, wherein:

Figure l is a. perspective view showing the manner in which the knife is held in the hand;

Fig. 2 is a perspective view of the knife and handle; and

Fig. 3 is a perspective view of the knife handle.

Referring to these figures, it will be seen that my knife handle, which is made of wood or other suitable material of like character, is formed with a relatively fiat rectangular body portion 10 rounded upon its outer edge face as at 11 and cut away at one corner as at 12 to form a thumb seat. The opposite corner is formed with the outwardly projecting boss 13 surrounded by the usual ferrule 14:, the shank of the knife 15 being inserted in this boss. Inward of the boss and on the edge of the body portion 10 opposite to the thumb rest or seat 12 there is formed a lug 16, which, as illustrated in Fig. 3, extends upward above the upper face of the body portion as at 17, the rear upper edge face being downwardly inclined. The pur pose of this lug 16 is to form a seat for the first and second fingers, the second finger bearing against the inclined face 18 of the Extending rearward from the body portion 10 is a portion 19 which is disposed in a plane at right angles to the plane of the portion 10. The under edge face 20 of this portion 19 is inclined upward and forward so that the forward edge of this face 20 is slightly above the under face of the portion 10. The portion 19 extends above the upper face of the portion 10 and the forward edge is upwardly and rearwardly inclined as at 21, then extends downward and slightly rearward as at 22, this face 22 merging into the upper edge face 23 of the portion 19.

In the practical use of the invention, the tool is held as illustrated in Fig. 1. The portion 19 is disposed in the palm of the hand, the hump 22 being engaged with the palm of the hand, the thumb lies along one edge face of the portion 10 with the end of the thumb resting in the seat 12. The first finger is extended over the forward edge of the lug 16, while the second finger extends below the lug and rests upon the inclined face 18. The third finger extends downward around the neck between the portion 20 and the portion 10, while the little finger simply surrounds the portion 19. Preferably, as illustrated in Fig. 1, the blade 15 is disposed at an inclination to the longitudinal axis of the handle and preferably this blade has a curved cutting edge. Of course I do not wish to be limited to any particular form of blade.

A knife having the handle above described, is particularly useful in cutting and trimming leather for the manufacture or repair of shoes. It is particularly good for trimming welts and working sole leather. This handle prevents the operator cutting himself and furthermore it has been found in actual tests that the operator can work more easily and do more work with this particular form of knife handle than he can with knives having handles as ordinarily made. Furthermore, it has also been found in actual practice that this handle will not blister the hands, and it is much less tiring to use than a knife having an ordinary handle. The knife cannot turn in the hand and therefore the grip on the handle does not have to be so strong. While I have illustrated a form of my inventionwhich has in practical use proved extremely effective, yet it is to be understood that the handle may be modified to suit it to various other purposes.

It will of course be obvious that this handle is intended to be made in diflerent sizes so as to suit large or small hands. Probably three sizes will be all that is necessary, and it is of course obvious that any desired material may be used for the handle,though preferably it will be made of wood.

Having described my invention, what I claim is: 7

1. A knife blade and a handle therefor having a relatively fiat body portion extending in a plane transverse to the plane of the blade, and a portion extending rearward therefrom and disposed in a plane at right angles to the body portion and parallel to the plane of the blade and adapted to be engaged by the palm of the hand, the first named body portion having a lug upon one edge and extending in a plane at right angles to the plane of the body portion adapted to be grasped between the first and second fingers of the hand.

2. A knife blade and handle therefor including a relatively flat body portion extending at right angles to the plane of the knife blade havin the forward corner of one edge cut away to form a rest for the thumb, the opposite edge of the bodyportion being formed with a laterally and upwardly projecting lug extending parallel to the plane of the blade and adapted to be grasped between the first and second fingers of the hand.

3. A knife handle of the character described including a relatively fiat body portion adapted to extend transversely to the plane of the knife, one edge of said body portion constituting a seat for the thumb and the other edge having a lug adapted to be grasped between the first and second fingers of the hand, there being an extension of the body portion rearward therefrom and adjacent the last named edge of the body portion, said extension being disposed in a plane at right angles to the plane of the body portion and having a protuberance upon its upper edge face with which the palm of the hand is adapted to engage.

d. A knife handle of the character described including a relatively flat body portion adapted to extend transversely to the plane of the knife, one edge of said body portion constituting a seat for the thumb and the other edge having a lug adapted to be grasped between the first and second fingers of the hand, there being an extension of the body portion rearward therefrom and adjacent the last named edge of the body portion, said extension being disposed at right angles to the body portion and having a protuberance upon its upper edge face with which the palm of the hand is adapted to engage, the lower edge of said extension at its forward end being formed to provide a neck between the body. portion and said extension adapted to be engaged by the third finger of the hand.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses. DANIEL J. LEFEBVRE. Witnesses:

EDWARD C. Lnrnevnn. MoRnAL O. VEINOT.
