WOODEN FILE HANDLE, DRIVE-ON (LONG FERRULE)
a) All files should be used with a handle
b) This is a general guide only because the tang sizes on files vary by file manufacturer
c) The file should fit in the handle so the base of the handle is either solidly touching the shoulder of the file or very close. No more than 10% of the length of the tang should be seen with the handle securely attached.
d) The handle is considered secure when it can not be pulled off the file by hand by the operator.
The following is a general guide only, because the tang sizes on files vary by file manufacturer. Oddly enough there are lots of government specifications on the files themselves but none on the tang portion other than what hardness they should be.
This kiln dried handle made of New England hardwood to avoid splitting, is stained and varnish coated. A ‘long ferrule’ style of heavy gage construction. The hole is step drilled to hold the wedge shaped file tang rigidly, locking the file in place. The file handle is driven on with a hammer and not intended for reuse. This handle meets all U.S. government specifications NN-H-00106c (GSA-FSS).
