PROBLEM TO BE SOLVED: To provide a snow surface walking tool with a slip preventor which has the function of preventing slipping and skidding in climbing up on ice or snow surfaces while enabling gliding on down hills. SOLUTION: One or a plurality of through holes 2 are arranged on the ground contact surface of each ski board while an anti-slip blade 4 and an anti-sideslip blade 6 are provided on the bottom surface side of the through holes 2 while being connected to a spring hinge 3 closer to the front of the walking tool. Both the blades are housed almost flush with the gliding surface when folded and the anti-slip blade sticks out at the right angle longitudinally with the spring action downward from the bottom surface of the ski board and the anti-sideslip blade 6 sticks out downward in the same direction with the spring action as required.
