Abstract

A knife sharpener comprises a scabbard 10 for receiving a knife blade 13. A sharpening device 11 is carried within the scabbard to engage a blade edge 14 within the scabbard 10 and can be moved manually along the scabbard to sharpen the blade edge 14. Thus, sharpening is accomplished while the blade is within the scabbard. A locking device 31 is provided to hold the blade within the scabbard 10. Part 46 of the scabbard 10 may be displaced to allow the sharpening device 11 to be removed for cleaning.
