I have some Ballpoints, Rollerballs and Pencils that have slippery metal grip sections. Until recently they have been frustrating to use for lengthy periods.
Last week I came up with a solution. First I removed the offending grip sections then cut and pushed appropriately sized pieces of heat shrink tubing over the shafts of the grips. Next I used a clean burning lighter to heat and shrink the tubing. Voilá . . . instant non-slip grip.
Note - on writing instruments with tapered grips the tubing can be slid on or off as desired.
Just a word of caution, ensure the grip section does not have a combustible inner liner or plastic parts that may melt or burn.
See photos of a slippery Kurutoga pencil and Sheaffer ballpoint that have been 'fixed' using this method.
I would appreciate hearing of other means FPNers have solved this issue.
