Simonds 73503000 Knife File 10in Bastard Double-Cut tool storage

Purpose and User

The Simonds 73503000 is a 10in knife file designed for shaping and smoothing aluminum, brass, bronze, steel and tin. Its rigid rectangular profile tapers toward the point for access in confined areas. The natural finish and double-cut faces suit machinists, metalworkers and maintenance technicians who need controlled material removal on flat or angled surfaces.

Build Integration

Three cut edges allow the file to work on adjacent faces without repositioning the workpiece, freeing bench space and reducing setup time. The 1in width and 11/64in thickness fit standard file handles and tool rolls. A bastard coarseness with 23, 27 and 31 teeth per inch balances stock removal and surface finish for general-purpose fitting tasks.

Sustained Use

The rigid body resists flex during long strokes, keeping the cutting geometry consistent across repeated passes. Single-cut edges help clear chips on the draw stroke, reducing loading on the double-cut faces. The natural steel surface resists corrosion in shop environments, maintaining cutting performance over extended sessions without clogging.
