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 Metal icon is a responsive icon. This means that it's optimized for four resolutions, from tiny 16x16 until highly detailed 80x80. The style comes from the latest Microsoft Office
, which makes it perfect for any Windows applications, in particular, those with ribbon toolbar control. Unlike other icon packs that have merely hundreds of icons, this monster icon pack contains 15,900 icons, all in the same style and quality.
