Fig. 1i is an enlarged transverse sectional view taken approximately on the line of ‘Fig. 3. Fig. '5 is an enlarged perspective view of the movable cutter element of the cutter unit" Referring to the drawing by characters of reference, A designates generally the cutter unit - and B the holder member therefor which mem ber consists of a hollow handle constituting a housing for a motor it diagrammatically illus trated in the present instance as an electrical mo“ 10 More particularly the invention resides in a tor and having a‘ shaft it, one terminal of which device of the indicated characterwhich includes ‘ extends into the groove it; formed at one end of fixed and movable cutter elements each having the handle.
