Century Dictionary and Cyclopedia
    • n sickle A reaping-hook; a curved blade of steel (anciently also of bronze) having the edge on the inner side of the curve, with a short handle or haft, for cutting with the right hand grain or grass which is grasped by the left. The sickle is the oldest of reaping-instruments, and still continues in use for some purposes, including in certain localities the gathering of crops. Sickles were formerly sometimes serrated, or made with sharp sloping teeth; the ordinary smooth-edged sickles are now sometimes called grass-knives or grass-hooks.
    • n sickle A sickle-shaped sharp-edged spur or gaff formerly used in cock-fighting.
    • n sickle In embryology, a crescentie thickening at the posterior edge of the blastodisc in certain vertebrate embryos with meroblastic eggs, such as the fishes and reptiles.
    • n sickle A crescentie whitish area in the choroid commonly observed in cases of myopia.
    • n sickle One of the arms; which support the yarn guide-wire, or faller, on the spindle-carriage of a spinning-mule: so named from its shape.
