Linoleum knives of different shapes and lengths that are inserted into a wooden handle. Usually used to cut out a design in a linoleum or rubber printing block. The blades are easy to insert and remove from the wooden handle. Insert the end of the blade into the wooden handle, then the wooden stick, then press lightly to secure the blade. Remove the knife by pressing the wooden stick again and then pulling it out. If you want a wooden handle for more than one knife, you can purchase them separately. Always make sure you cut away from yourself as the blades can be extremely sharp.
