A multipurpose snow tool for backcountry travel being a modified ice ax having a toothed pick at one end, an adze at the other and a shank therebetween having holes therein large enough to reduce weight without compromising structural integrity. The shank having shock absorbing upper spacers thereabout for insertion into the upper portion of a shaft of varying length depending upon user's physique. Lower spacers surround a combined reversible integrated spike saw held within said shaft, said spacers enclosing a pair of locking buttons supported by leaf springs to secure the spike saw in the lower shaft and to permit easy withdrawal therefrom and reversal for saw use. Furthermore, the invention includes a shovel blade having a sleeve like projection sized to snugly fit around the lower portion of said shaft which is always ready for use when attached while said spike is exposed. Thus, by depressing both buttons simultaneously, the spike saw is removed and reversed. When the spike is in the exposed position, the shovel blade can be quickly attached with a leashed bolt and wing nut.

1. A multipurpose ice ax for backcountry travel comprising:a head having a toothed pick at its first end and an adze at its second end with a shank therebetween; a hollow shaft having holes therein its upper end to internally receive said shank having matching holes therein and locked in place with pins, said shaft having holes therein its lower end for internally receiving a combined reversible spike saw having matching holes therein said spike saw comprising a spike and a saw; shock absorbing upper spacers having holes therein for connecting said shank of the head within said upper end of said shaft for reducing the shock of said shank against said shaft when the force of the head impacts snow and ice; lower spacers having holes therein for connecting and rigidly fixing said spike saw within said lower end of said shaft selected from the group consisting of rubber, plastic, steel and aluminum; means for reversing said spike saw to expose said spike or said saw as necessary; and a shovel blade having a blade portion and a sleeve like portion having holes therein carried separately from the integrated multipurpose ice ax and attachable to said lower end of said shaft by means of a shovel fastener inserted through matching holes of said shaft and said sleeve like portion while said spike saw is housed within said shaft with said spike exposed.
