clamping the blade in position in said opening, means engaging a back edge of the blade for adjusting the position of the blade in the opening, and a projecting handle on said blade to facilitate positioning thereof, substantially as described.

4. In a linoleum cutter, a blade receiving member having a kerf formed therein and intersecting the lower face thereof, means operable in one direction for clamping a blade in position in said kerf, and means operable at substantially right angles to said first mentioned means for adjusting the posi-` tion of the blade in said kerf, substantially as described. L

5. In a linoleum cutter, a blade carrying member having a linoleum engaging face provided with a projecting guide rib, there being a blade receiving opening intersecting said face, a blade in said opening having a horizontally extending handle portion and a vertically extending cutting portion and means for clamping the blade in position in said opening, substantially as described.

6. In a linoleum cutter, a blade carrier having a longitudinally extending kerf adapted to receive and support the blade of a standard linoleum knife, and means for mamtaining a standard linoleum knife in operative position in said ker, substantially as described.

7. In a linoleum cutter, a blade carrier, an operating handle projecting therefrom, and means for clamping a standard linoleum knife in operative relation to said carrier, substantially as described.

8. In a linoleum cutter, a blade carrier of generally elongated form having a longitudinally extending kerf formed therein and intersecting the bottom face and one end of the carrier only, a linoleum knife having its blade inserted within said kerf and havlng its handle portion `substantially in longitudinal alignment with the carrier, and means for clamping said blade in position in the kerf, substantially as described.

9. In a linoleum cutter, a blade carrier of generally elongated form having a longitudinally extending kerf Aformed therein and intersecting the bottom face `and one end of the carrier only, a linoleum knife having its blade inserted within said kerf and having its handle portion substantially in longitudinal alignment with said carrier, and means for clam ing said blade in position in the kerf, sai carrier having guiding means projecting therefrom adjacent one side of and substantially parallel to the kerf for engaging one edge of the material being cut, substantially as described.

10. In a linoleum cutter, a blade carrier of generally elongated form having a longitudinally extendingkerf formed therein and intersecting the bottom face and one end of the carrier only, a linoleum knife having its blade inserted Within said kerf and having its handle portion substantially in longitudinal alignment with the carrier, and means for clamping said blade in position in the kerf,`said carrier having a pair of operating handles formed thereon, one of said handles being adjacent each end of the carrier, substantiallly as described.
