This is a Push Pin 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 13,000 icons, all in the same style and quality.
This logo is representative of a push pin. It has a thin line protruding from a shape that is similar to an hourglass. The line represents the sharp part of the pin and the hourglass represents the part you grab with your hand to push it into whatever you'd like to adhere.
