This is the Odblokować 2 icon for Windows 10. Here we go. Optimized for 32x32 px, these are the simplest icons in the line style. Downloadable formats are PNG and SVG, among others. Icons8 icon pack is unique in providing a huge number of icons designed by the same team of four designers who create the new icons every working day in the same style and with the same quality. Same cool as the Bat Face, huh.
It's an icon of a lock. There is a circle to represent the lock mechanism, with a small black circle with a rectangle extending from the bottom to represent the keyhole. A curved line extends from the top left of the large circle, and arches almost all the way to the right, to represent an open lock.
