摘要： A scissors sharpener including a pair of elongate sharpening elements (12) relatively arranged so as to define a vee shaped sharpening recess (13) between them. Each sharpening element (12) forms a respective one of two sides of the recess (13) and each side has a longitudinal extent which is no less than the length of the scissor cutting edges (6) to be sharpened. At least one of the sharpening elements (12) is mounted so as to be movable laterally away from the other element (12), and resilient means (17) bears against the movable element (12) so as to resist the aforementioned movement. The sharpening elements (12) overlie a base plate (15) and an extension of that plate forms a platform (32) against which the handle portion (33) of scissors (1) can rest during the sharpening operation. In use, scissors (1) are located on the sharpener (11) with the closed blades (2,3) over the recess (13) and the cutting edges (6) extending generally in the longitudinal direction of the recess sides. Sharpening is effected by moving the closed blades (2,3) sidewards through the recess (13) towards the underlying base plate (15) so that each cutting edge (6) engages and is treated by a respective sharpening element (12) during that movement.

摘要： A retractable blade knife having a self-sharpening facility (34) which can be selectively rendered inoperable. The sharpener (34) is spring biased in an upward direction so as to be urged into engagement with the cutting edge (17) of a knife blade (10), and manually operable release means (38) is provided to permit the sharpener (34) to be held in an inoperable position. An assembly of which the sharpener (34) forms part also functions as stop means which positively prevents movement of the knife blade (10) into its extended position. Such extension is possible only upon operation of the release means (38), but that is only necessary during initial outward movement of the knife blade (10). The sharpener (34) is arranged to sharpen the cutting edge (17) of the blade (10) up to the tip (19) of the blade (10). Positive locking means (27) is provided to prevent inward movement of the blade (10) when working under load in the extended position.
摘要翻译：一种具有可以选择性地不可操作的自锐化设备（34）的可伸缩刀片刀。该磨刀器（34）沿向上的方向被弹簧偏压，以被推动与刀片（10）的切割刃（17）接合，并且提供手动操作的释放装置（38）以允许磨刀器（34））将处于不能操作的位置。磨刀器（34）形成的组件也用作止动装置，其可以有效地防止刀片（10）进入其伸出位置的运动。只有在释放装置（38）的操作时，这种延伸才是可能的，但是仅在刀片（10）的初始向外移动期间才需要。磨刀器（34）被布置成将刀片（10）的切割刃（17）磨削直到叶片（10）的尖端（19）。设置有正的锁定装置（27），以防止在延伸位置的负载下工作时叶片（10）向内移动。
