Amundenout `boss vv5I). isformed-1ateaoh of the` upper cornersoi-the memherul. Theiovier sideofeaoh shown in Figs. 3 and 7. It will be noted that when the blade is in the operative position as shown in Fig. 3 the notched corners will receive the bosses 50 to prevent any material longitudinal movement of the blade and will also preclude any vertical transverse movement thereof. Plain bosses 54 adjacent each of the opposite lower corners of the member l are so related to the lower corner notches 44 of the blade 38 as to permit the bladetobejlaid flat on the surface i6 for adjustmentintonotches.52.

When the blade is in the operative position as shown in Fig. 3 it will be noted that the upperA corners of the blade are slightly below the upper ends of bosses 50 and the lower corners of the blade are slightly above the lower extremities of bosses 54, thereby guarding the injury to the operator. The upper edge of blade 38 is spaced inwardly from the outer edge of member I0. The blade shown is of the double cutting edge type which has a central opening 56 which extends lengthwise thereof and has an enlargement 58 adjacent the central portion of the'blade. The central portion of the blade-supporting member is provided with an undercut boss 60 having an overhanging lip 62 which overhangs the blade about enlargement 58 to prevent the upward movement of the central portion of the blade when itis inthe operative position. '.The depth ofthe undercut notch'64 in boss 60 is much greater-than the depth of notches 52 so that whenthe Iblade is fully seated in notches 52 in bosses 50 the blade metal about opening 58 will not contact the bottom of notch 64m boss 60.`

f'One'of the principal objects of the present invention is to secure the blade in position 'on the blade-supporting member by means of a magnet or a fiplurality of magnets, and Vfor the purpose of` controlling and properly applyingthe magnetic force it has been found expedientto make the handle and blade-supporting member of a non-ferrous material.

The magnetGS, best shown in 'perspective in Figf, is rectangular in shape cut away on one dif-its faces to produce four pole pieces 6B whichV are adaptedA to be snugly tted into openings 10 formedthrough the body' of member I0 so that the surface of the poles will .be in the plane` of the blade bearing surface I6. The magnet is preferably of the permanent type and' can be made of any suitable material. r Many4 alloys have been` developed that have extremelyhigh magnetic yqualities and vwhen these alloys are used smaller magnets will have suicient force of pull to hold the blade in position.

The magnets may be molded, formed or otherwise vproduced and are I secured in position by meansof rivets 12 fitted into hole 14 and extendingthrough a hole formed through the member 'I n the present showing two similar magnets are shown, one on each side of the handle. -f

` The double-edge blade is so constructed tha l it can be turned over or the edges reversed. Sin-y glie-edged blades or substantially any type of blade made of a magnetic material can 4be used iny conjunction with this type of blade holder since the principal requirement is that thefblade 'ber having-spaced apart bosses atits opposite ends, to receive a blade therebetween for limited transverse and longitudinal movement, and a permanent magnet carried by said blade-support ing member whereby said blade is secured in the operative position between said bosses.
