Abstract: A hoe for facilitating working on at least two sides of a plant simultaneously which comprises a handle, a shank, a ferrule, and a blade. The blade has a first inner angled edge of a first outcrop, and a second inner angled edge of a second outcrop which form between them a substantially V-shaped opening. A flat inner edge cuts off the inner point of the substantially V-shaped opening. The substantially V-shaped opening is for partially encompassing a plant for uprooting, as well as for forming parallel furrows, the sides of which are formed by the inner angled edges as well as by outer angled edges of the blade.

Abstract: A drainable oil filter for an engine of a motor vehicle which comprises a cylindrical canister having a closed first end and a second end adapted to be screwed onto the engine of a motor vehicle. A mechanism on the closed first end of the cylindrical canister is for draining residual oil from the cylindrical canister. After oil in a crankcase of the engine of the motor vehicle is drained and before the second end of the cylindrical canister is unscrewed from the engine of the motor vehicle, the draining mechanism when operated by a person will allow the residual oil in the cylindrical canister to exit safely therefrom into a suitable container, without soiling the person positioned under the draining mechanism.
