    • 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.
    • 一种剪刀磨刀机,包括一对相对布置成在它们之间限定一个形状锐利的磨削凹槽(13)的细长磨刀元件(12)。 每个磨削元件(12)形成凹部(13)的两侧中的相应一个,并且每个侧面具有不小于要被削尖的剪刀刃(6)的长度的纵向长度。 至少一个磨边元件(12)被安装成能够横向远离另一个元件(12)移动,并且弹性装置(17)抵靠在可移动元件(12)上,以抵抗上述移动。 磨削元件(12)覆盖在基板(15)上,并且该板的延伸部形成平台(32),剪刀(1)的手柄部分(33)可在磨削操作期间保持。 在使用中,剪刀(1)位于磨刀器(11)上,封闭刀片(2,3)位于凹槽(13)上,并且切割刃(6)大致沿凹槽侧的纵向方向延伸。 通过将封闭的刀片(2,3)朝向下方的底板(15)侧向移动通过凹槽(13)来实现锐化,使得每个切削刃(6)接合并由相应的磨削元件(12)处理,在此期间 运动。
