This is our Fusion Small, Fine equaling file. This is one of Bob’s favorite files for working the inside edges of the Slide stop window, Mag-well top & Bottom and other internal flat areas of the 1911 frame. Also, used to corner break the edges internal to the slide and polish the breech face with the use of fine emery paper wrap. This is a great “all-around” file for many applications. Size: .060 thick, x .225” Width x 5.5” overall length.
