Vallorbe® Pillar Checkering Files

The Vallorbe® Pillar Checkering Files are used to make “Jimping” on the spine of a blade.

It provides a better grip by giving the user’s thumb (or sometimes an index finger) something to bite into as it slips over the blade while working the knife. A checkering file is used to make true, accurate line spacing when checkering backstraps, trigger guards, grip frames, ribs and hammer spurs; anywhere an improved gripping surface is needed. Finer cuts give a nice matting effect to reduce glare and light distortion.

The procedure is very similar to wood checkering. Layout your master lines, then establish the pattern by moving the file a few teeth each time using the previous lines as the guide. Once the pattern is fully laid out, bring to final depth with a 60° needle file.

Notches down the spine of a blade created to provide a grip on a knife beyond the bolster. Many knives, especially pocket knives, have very shallow or widely spaced non-functional notches that are used solely for aesthetic purposes.

These larger files are ideal for jimping/checkering on the spine of larger pocket knife blades and large fixed-blade knives.
