This is a Konewka icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 12,100 icons, all in the same style and quality.
This icon is a watering can. The body of the can is a partial square with the right angle being at the top right. Over the right angle of the square is a curved line for the handle. On the left side of the partial square is a protruding rectangle shape with a rounded edge, meant to be the portion of the can that lets out water.
