The icon is an anvil. The anvil has a metal base at the bottom with two feet. The top of the anvil is flat with a curved bottom, and there's another part sticking out from the side with a pointed end and a curved bottom.
This is a Metal 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 13,300 icons, all in the same style and quality.
