PROBLEM TO BE SOLVED: To solve the conventional problem that a finger slippage occurs or a pain is felt on the palm side of a finger depending upon the size of a knurl, that is, a writer has a feel of incongruity with an uncomfortable touch of the grip during writing so that the grip is not suitable for a practical use and therefore, there is still room for further development of a new grip. SOLUTION: This grip is provided on a barrel and has a knurled surface, the pitch of the knurls being 0.4 to 0.7 mm. |
