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.
