3 Claims.

This invention relates to cutlery, and contemplates a blade for cutlery articles designed especially for woodcarving. The special feature of the blade is that it effectively combines functions of scraping and cutting.

In the drawing:

Fig. 1 is a front elevation of a pocket knife, shown as a typical cutlery article to which the novel blade may be applied.

Fig. 2 is an enlarged rear elevation of the blade detached.

Fig. 3 is a section substantially on the line 3-3 of Fig. 2.

Fig. 4 is a section substantially on of Fig. 2.

r Fig. 5 is a section substantially on the line 5-5 of Fig. 2.

Fig. 6 is a section substantially on the line 6-5 of Fig. 2.

The blade identified generally by numeral Ill comprises a scraping edge I l substantially parallel to the back l2 and a cutting edge [3 disposed at an angle to the scraping edge I l. The back l2 may terminate in an angularly disposed surface M meeting the cutting edge l3 in a sharp point. The body of the blade opposite the greater portion of the length of the scraping edge II is of substantially the same thickness from the back [2 to a point adjacent the scraping edge I I, as clearly shown in the sections in Figs. 3 and 4; that is, oppositely disposed faces l5 and 16 are substantially parallel. The scraping edge H is preferably in the plane of the face l5, and clearance back of the scraping edge is provided by grinding from the margin of face l5 toward face 16 at a relatively large angle, say about 35, forming the surface H. The blade has the same crosssectional configuration through the major portion of its length, as indicated by the similarity of the sections at lines 3-3 and 4-4 of Fig. 2. A sturdy and efficient scraper is thus provided.

Toward the free end or the blade each of the faces l5 and I6 is ground off to form faces l8 and I9, respectively. The face l8 intersects a plane substantially parallel to and midway between the the line 4-4 planes of faces I5 and I6, and intersects the face 15 in the oblique line 20. The face I9 similarly intersects the face 16 in the oblique line 2| and the aforementioned medial plane. The intersection of faces l8 and I9 forms the obliquely disposed cutting edge l3, said faces meeting at the usual relatively small angle, as distinguished from the large angle which defines the scraping edge. II. There is thus secured a unitary blade member comprising both an effective and properly backed scraping edge ll and an efficiently designed and arranged cutting edge l3.

It will be obvious that the invention is susceptible to other embodiments, all falling within the scope of the appended claims, which claims are to be broadly construed.

What is claimed is:

1. A knife blade comprising as a major portion thereof a body of substantially uniform thickness throughout its length and a major portion of its width, said body terminating laterally in a scraping edge in the plane of one face of the body, the body being ground from said scraping edge to the opposite edge at an angle sufficient to provide clearance for said scraping edge, said blade comprising a cutting edge formed by grinding each of said faces to a plane: which obliquely intersects both the face and a plane intermediate said faces.

2. A blade comprising substantially parallel faces, a scraping edge in the plane of one of said faces formed by an edge defining face extending obliquely to said parallel faces, and a cutting edge formed by the grinding of said parallel faces in intersecting planes each of which intersects one of said faces in a line oblique to said scraping edge.

3. A blade comprising substantially parallel faces, a scraping edge formed by an edge defining face extending obliquely to said parallel faces, and a cutting edge formed by the grinding of said parallelv faces in intersecting planes each of which intersects one of said faces in a line oblique to said scraping edge.
