This invention has relation to hay-knives; and it consists in the construction and novel arrangement of the'square cutting-plate having four cutting-edges meeting in as many points and eight perforations circularly arranged around a central aperture, and the handle having a pivot connecting it to the center of the plate, and a movable pin-fastening, whereby the position of the plate or blade may be fixed after adjustment, all as hereinafter set forth. In the accompanying drawings, the letter A designates a square plate of steel, having a central aperture, 1), for the passage of the pivot-bolt 0, whereby it is connected to the handle D. The "plate is formed with four. cuttingedges, 6, meeting in as many points 9, and has eight perforations, h, circularly and regularly arranged around the central or pivotal aperture, b, so that each perforation h is in line the perforations of the blade.
after adjustment, a screw or pin, k,is provided,
which extends through the handle into one of v The handle is designed to be provided with a step, Z, which is in such position with reference to the blade that the cutting-edges of the latter can be ground with facility.
This instrument is designed to serve many ,useful purposes, and can be made very strong and durable. It is advisable, in order to avoid too frequent sharpening, to keep two ofits cut: tingedges for hay, the other two being used for cutting turf, roots, 82c.
Having described this invention, what I claim, and desire to secure by Letters Patent, 1s The hay-knife consisting of the square blade having four cutting-edges meeting in as many points and eight perforations circularly arranged around a central aperture, the handle having'a pivot connecting it to the center of the blade, and a movable fastening adapted to engage one of the circular series of perfora-fi tions to secure the blade in position, substantially as specified. v
In testimony whereof I affix my signature in presence of two witnesses.
