This invention relates to improvements in and the like, it will be noted that in the present knives. -A knife embodying this invention is device the head ridge II and the ridges l2 and particularly adapted for use as a paring knife or iii are convergent, and it will also be noted that carving knife. the ridge I3 is elongated as compared with ridge 5 It is the object-of the invention to provide a I2 (see Fig. 1).

While such ridges b e. In y ot e ves. attempts have 66 have heretofore been provided on knife handles been madeto limit the movement of the operators hand over the back of the blade by means of some sort of support located at the extreme end of the handle adjacent the blade. In such knives, however, there is not the freedom of manipulation nor the security of support that is provided by fixing the position of the operators hand with a fin located between the first and second fingers "instead of outside of the first finger.
I claim:
1. In a knife, the combination with a blade having a cutting edge and a back edge, of a handle connectedwith said blade and bevelled at its end to extend farther along the back edge handle connected with said blade and bevelled at its end to extend farther along the back edge than along the cutting edge of the blade, all sides of saidhandleconvexly approaching said blade,
together with a fin spaced from the end of said blade for the width of the operator's forefinger and inclined with reference to said handle sufl-' having a cutting edge and a backedge, of a ciently to approach parallelism with the beveled end thereof.
3. The combination with a knife blade having aback and a cutting edge, of a handle connected with said blade and provided with a fin spaced from said blade upon said handle for approximately only the width of the operator's forefinger, said fin projecting laterally from the handle suf-- ficiently to be received between the operator's first and second fingers to facilitate his grip upon the handle in the manipulation of the knife, and said fin being substantially continuous with a rela-. tively thin cross section acrossone side of the handle from that portion of the handle adjacent the back of the blade to that portion of the'handle adjacent the cutting edge thereof,-
