Abstract

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

Claims

1. Hand held cutting device, comprising a handle and a cutting head, a cutting element attached to said cutting head, a guiding and supporting element extending from said cutting head, said guiding and supporting element and 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 none rotateably, fixedly attached to said cutting head, by means of a locking device that provides for at least three different re-positioning and thereby renewing of said cutting edge.

2. A hand held cutting device according to claim 1, 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.

3. A hand held device according to claim 2, 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.

4. A hand held device according to claim 2, wherein said support device is in a form of a sleeve arranged to fit on a core element of said guiding and supporting element.

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

6. 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 cutter head.

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

8. A hand held device according to claim 1, wherein said cutting element is positioned within a recess of said cutting head and that is arranged at least one bevelled portion of a side sidewall of said recess, to facilitate for the cut material to leave the cutting head without risk of clogging at the exit of the recess.

9. 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.

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

11. A hand held device according to claim 9, wherein an integral glide stop is arranged at a distal end of said core portion.
