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 users 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 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.
