Description

Patented July 21, 1936 ETED STATES PATENT OFFICE 3 Claims.
This invention relates generally to cutlery and particularly to an improved form of paring knife.
The main object of this invention is the con- .struction of an improved form of paring knife which will facilitate the paring operation by curving the cutting edge to conform generally with the contour of a rounded object and to place the cutting edge approximately on a line with the back edge of the knife handle at which line the force of the hand is applied.
The second object is to so construct the knife that notwithstanding the curved cutting edge, there will be a uniform increase in the flexibility of the blade from the handle toward the point of the blade.
The third object is to so construct the knife that the advantages of the pointed blade are not lost.
These, and other objects, will become more apparent from the specification following as illustrated in the accompanying drawing, in which:
Fig. l is a side elevation of the knife.
Fig. 2 is an edge elevation thereof. 7
Fig. 3 is a section taken along the line 33 in Fig. 1.
Fig. 4 is a section taken along the line 4-4 in Fig. 1.
Fig. 5 is a section taken along the line 55 in Fig. 1.
Fig. 6 is an elevation of the knife taken from the point end.
Similar numbers of reference refer to similar parts throughout the several views.
Referring in detail to the drawing, there is shown a handle from which projects a blade H whose cutting edge l 2 is curved so that the middle portion i3 is approximately in a line with the rear side M of the handle I0. The tip 15 is preferably pointed as shown and the rear edge It of the blade II is substantially parallel with the cutting edge l2, although the blade I I tapers gradually from the handle ID to the tip I5.
It will be noted that the portion I! of the cutting edge l2is curvedin a reverse manner to the middle portion l3. While the middle portion l3 of the cutting edge l2 has been shown substantially in alignment with the edge [4, it is obvious that it could be placed on either side of this line without departing from the spirit of this invention, although it is desirable to have the actual cutting edge close to the line of the rear side M as it facilitates the guiding of the blade along the inside of the peel.
In some instances, it may be desirable to reduce the width of the blade ll along the section 4-G, although it is desirable to retain as much material at this point as is possible to offset the 10 Wear caused by sharpening.
I am aware that various forms of paring knives have been constructed in the past and that knives have been constructed with curved cutting edges. I therefore do not intend to cover this device broadly but limit myself to the forms particularly set forth in the accompanying claims.
I claim:
1. A paring knife having a. blade which tapers in thickness toward its point and having its cutting edge in the form of a reversed curve with a concave portion near the middle thereof and a convex portion toward the point, the middle of the concave portion and the point of the knife being substantially in alinement with the rear edge of the knife handle.
2. A paring knife having a blade which tapers in thickness toward its point and having a concavely curved cutting edge extending approximately to the line of the rear edge of the knife handle and having the rear edge of the blade substantially in parallelism with the cutting edge thereof and having the rear edge and cutting edge converging to form a point, said point being
