Simonds 4-inch Knife File

The Simonds 73498500 is a 4-inch American pattern knife file designed for shaping and finishing metal surfaces. Its rectangular profile tapers toward the point, allowing access to tight angles and slots. The tool suits machinists, metalworkers and hobbyists who need precise material removal on aluminium, brass, bronze, steel and tin.

Double-cut faces with single-cut edges

Three cutting edges feature a double-cut face pattern and single-cut edges, providing aggressive stock removal while leaving a smoother finish on the flats. The bastard cut coarseness and rigid body resist flexing during heavy strokes. A natural finish protects the steel without adding thickness that could interfere with close work.

Sustained cutting across varied metals

Teeth-per-inch counts of 40, 44, 54 and 58 across the cutting surfaces maintain consistent bite during prolonged filing sessions. The rigid construction prevents the blade from springing under continuous pressure, keeping the cut true on hard steels as well as softer alloys. The file retains its geometry without the rapid dulling seen on finer-pattern tools.

Questions about this item

How long will the 4 in knife file stay sharp when used all day on steel?

The file has a bastard double-cut face with 40 to 58 teeth per inch and three cutting edges, so it removes material steadily on steel without clogging.

Does the file get hot or vibrate in the hand during continuous filing?

The rigid rectangular body is 5/64 in thick and 7/16 in wide, so it resists flex and runs cool even under steady pressure.

What handle or holder do I need before I can use this file?

The tang is unhandled, so you must supply a standard file handle that fits a 4 in American-pattern knife file.
