Introducing the Eternal Tools Fine 600 Grit Oval Diamond Needle File. 140mm x 70mm. Similar to a Crossing diamond rasp, the cross-section of an oval file differs in that it follows a more conventional oval shape (unlike a Crossing file, which is pointed at the edges).

Oval files offer versatility in filing, as they can be used with their broad, convex faces for general filing purposes and edge-on to file inside steep concave grooves. This dual functionality makes oval files valuable tools for addressing a wide array of filing needs.
