Claims

1. A saw having a handle and a blade projecting from the handle, the blade having an edge along which a plurality of saw teeth project, the saw further including a flexible and retractable saw guard which is connected to the saw and which is retractable from a guard position in which the saw guard overlies the saw teeth and a retracted position in which the saw teeth are exposed.

2. A saw according to claim 1 , the saw guard being connectable in the guard position to an end of the saw blade remote from the handle.

3. A saw according to claim 2, the end of the saw blade remote from the handle being an end edge of the saw blade.

4. A saw according to claim 3, the end edge of the saw blade being at the end of the edge along which the plurality of saw teeth project.

5. A saw according to claim 3, the end edge of the saw blade being an edge that extends laterally to the edge along which the plurality of saw teeth project.

6. A saw according to claim 3, the end edge of the saw blade being an edge which is opposite to the edge along which the plurality of saw teeth project.

7. A saw according to any one of claims 2 to 6, the saw guard including an end connector for connection to an end of the saw blade remote from the handle.

8. A saw according to claim 7, the end connector being operable to releasably cooperate with a notch, recess or opening formed in the saw blade in the guard position.

9. A saw according to any one of claims 1 to 8, the saw guard having a channel into which the edge along which the plurality of saw teeth project extends in the guard position.

10. A saw according to claim 9, facing surfaces of the channel gripping opposite side surfaces of the saw blade in the guard position.

1 1 . A saw according to claim 1 , the saw including a frame that extends from the handle to an end of the saw blade remote from the handle and the saw guard being connectable in the guard position to a portion of the frame remote from the handle.

12. A saw according to any one of claims 1 to 1 1 , including a retraction mechanism which connects the saw guard to the saw and which facilitates retraction of the saw blade from the guard position.

13. A saw according to claim 12, the retraction mechanism facilitating automatic retraction of the saw guard once the saw guard is released from the guard position.

14. A saw according to claim 12 or 13, the retraction mechanism including a spool for retracting the saw guard.

15. A saw according to claim 14, the spool being a spring biased spool which applies a permanent retraction load on the saw guard.

16. A saw according to claim 14, the spool being a manually retractable spool.

17. A saw according to any one of claims 14 to 16, the retraction mechanism including a line connected to the spool and to a proximal end of the saw guard so that as the saw guard retracts, the line wraps around the spool.

18. A saw according to any one of claims 1 to 17, the handle being hollow or semi hollow and the saw guard being retracted to within the handle in the retracted position.

19. A saw according to any one of claims 14 to 18, the handle having a hollow or semi hollow interior and the spool being housed within the interior.

20. A saw according to claim 18 or 19, a track being housed within the interior of the handle about which the saw guard is retracted.

21 . A saw according to claim 20, the track being arranged so that the saw guard forms a loop, coil or spiral within the interior of the handle in the retracted position.

22. A saw according to claim 20 or 21 , the track being formed as part of a cartridge positioned within the interior of the handle.

23. A saw according to any one of claims 1 to 22, the saw guard comprising a plurality of links that are hingedly connected together to form an elongate chain.

24. A saw according to any one of claims 1 to 23, including a tensioning device to apply tension to the saw guard when the saw guard is in the guard position.

25. A saw according to claim 24, each of the tensioning device and the saw guard including abutments for cooperating engagement in the guard position of the saw guard, the abutment of the tensioning device being biased in a direction to apply tension to the saw guard when the saw guard is in the guard position and the abutments of the tensioning device and the saw guard engaging during extension of the saw guard to the guard position.

26. A saw according to claim 24, each of the tensioning device and the saw guard including abutments for cooperating engagement in the guard position of the saw guard, the abutment of the tensioning device being biased in a direction to apply tension to the saw guard when the saw guard is in the guard position and the abutments of the tensioning device and the saw guard engaging upon the saw guard reaching the guard position.

27. A saw according to claim 25 or 26, the abutment of the tensioning device being biased by a coil spring.

28. A saw according to claim 27, the coil spring being mounted at one end against an abutment of the saw handle and against the opposite end against the abutment of the tensioning device.

29. A saw according to any one of claims 24 to 28, the handle being hollow or semi hollow and the tensioning device being located within the handle.
