Abstract

This invention relates to a hand held cutting device comprising a handle (62), a cutting head (63), a cutting element (4) attached to the cutting head (63), and a guiding and supporting element (2) extending from the cutting head (63). The guiding and supporting element (2) and cutting head (63) are arranged to form a protecting periphery (100) such that any part of a cutting edge (4A) of the cutting element (4) does not protrude outside of said periphery. The guiding and supporting element (2) includes a distal portion (2A) arranged to form a feed channel (64) together with a portion (60) of the handle (62) and a support device (1) is arranged on the guiding and supporting element (2). The support device (1) is arranged to interact with the cutting edge (4A) to improve cut ability, wherein the cutting element (4) is arranged to be none rotatably, fixedly attached to the cutting head (63) by means of a locking device (40, 41) that provides for at least three different re-positioning and thereby renewing of the cutting edge (4a).

Claims

1. A hand-held cutting device comprising:

a handle attached to a cutting head;

a cutting element attached to said cutting head; and

a guiding and supporting element extending from said cutting head, said guiding and supporting element and said cutting head arranged to form a protecting periphery such that any part of a cutting edge of said cutting element does not protrude outside of said periphery, said guiding and supporting element including a distal portion arranged to form a feed channel together with a portion of said handle and a support device arranged on said guiding and supporting element, which support device is arranged to interact with said cutting edge to improve cut ability, wherein said cutting element is arranged to be non-rotatable and fixedly attached to said cutting head by means of a locking device that provides for at least three different positions and thereby renewing of said cutting edge, and wherein said support device is arranged with a portion made of a softer material than the material of said cutting edge to form a fixed recess interacting with said cutting edge.

2. A hand held device according to claim 1, wherein said portion is provided with a smoothly curved, low friction surface that provides for a substantially clog free converging zone of the feed channel.

3. A hand held device according to claim 1, wherein said support device is in a form of a sleeve arranged to fit on a core element of said guiding and supporting element.

4. A hand held device according to claim 3, wherein said support device is wholly made of said softer material and arranged with a snap-in arrangement to securely attach the sleeve.

5. A hand held device according to claim 1, wherein said guiding and supporting element includes a core element, fixedly attached to the body of the cutting head.

6. A hand held device according to claim 1, wherein said guiding and supporting element includes a core element integral with the body of the cutting head.

7. A hand held device according to claim 1, wherein said cutting element is positioned within a recess of said cutting head, said recess having a first end and a second end such that a sidewall is located adjacent said second end, and wherein said sidewall has at least one bevelled portion to facilitate for the cut material to leave the cutting head without risk of clogging at the exit of the recess.

8. A hand held device according to claim 1, wherein said handle comprises a core portion having at least one through hole for a finger of a user.

9. A hand held device according to claim 8, wherein at least one easily attachable/detachable cover plate is arranged on to said core portion.

10. A hand held device according to claim 8, wherein an integral glide stop is arranged at a distal end of said core portion.
