PROBLEM TO BE SOLVED: To increase safety in using a stick by fitting the stick body with a winter slip preventer suited for use during the snow season to prevent slip on snow-covered or frozen road surfaces and to make the stick lightweight, nonbulky and convenient to use by fitting the stick with a summer slip preventer suited for use during the summer, spring and fall other than the snow season to prevent slip on dry and wet road surfaces. SOLUTION: A rubber slip preventer 2 is provided at the lower end of the stick body 1. The slip preventer 2 is replaceable with the winter slip preventer 3 suited for use during the snow season and the summer slip preventer 4 suited for use during the other seasons.
