Precision Filing Tool

The Simonds 73500000 Knife File is a 6in American pattern hand tool designed for shaping and finishing aluminium, brass, bronze, steel and tin. Its rectangular profile tapers toward the point with a rigid body suited to detail work in tight spaces. The natural finish and box container protect the cutting surfaces before use.

Hand Tool Operation

As a manual file, it generates no motor noise, vibration or electrical power draw during normal use. The double-cut face with single-cut edges and a coarseness rated between 30 and 50 teeth per inch provides controlled material removal. The 7/64in thickness and 5/8in width give a balanced feel for sustained hand pressure.

Sustained Use Behaviour

Under continuous filing the rigid construction resists flex while the three cutting edges maintain consistent engagement across the workpiece. The bastard cut grade clears swarf efficiently without clogging on softer metals like aluminium or brass. Performance remains steady until the teeth eventually dull through extended abrasion.

Questions about this item

How do I install the 6 in knife file and what step is often missed?

The file ships ready to use; the common mistake is skipping the handle — fit a tang handle before applying pressure to the 5/8 in wide, 7/64 in thick blade.

What maintenance or replacement will the double-cut knife file need later?

Clean the 30, 34, 46, 50 TPI teeth with a file card after each use; when the bastard-cut edges no longer bite aluminum, brass, bronze, steel or tin, replace the file.

What limit appears first during sustained filing with this rigid rectangular file?

The three cutting edges dull before the natural-finish steel body shows wear, so cutting efficiency drops first on long jobs.
