A multifunctional walking staff, to aid in balance and support on an ice surface, and to function as a survival or a rescue tool in the event of breaking through thin ice into water. Secure traction on ice is attained by a metal tip, which may be further pressed onto the ice by a foot peg, serving also as a grapple hook. Secured onto the ice, the staff affords reliable anchorage to an attached rescue line, which is ordinarily stowed in multiple folds therewithin. An adjustable loop is formed integrally with, or adjoined to the rescue line, which loop may be manoeuvred by the staff to facilitate engagement with the rescuee. A buoyant projectile linked to the loop is releasably disposed within a top section of the staff, and is of such weight that it and the loop may jointly be cast the full extent of the rescue line. |
