Designed to be 0.5 oz each, so you can carry 4 of them for 2 ounces. Supplementing your 4 snow stakes with hiking poles, ice axe, and/or snowshoes should allow you to stake out any shelter in winter conditions with a minimal weight penalty.
To use these snow stakes, find an area of snow which is large enough to accommodate your shelter. Using your feet/snowshoes, stomp down the snow to compress it. Give it some time to "set" and harden, then erect your shelter using the snow stakes. Throughout the evening and night, the snow will harden around and through the holes in the snow stakes.
Features include the following: Thin top handle is designed to allow the user to insert the snow stake deep in the snow. The top of a snow stake handles less of a load than the bottom and therefore a larger section on top is not required. The second feature is the cutting edge t-wrap located just below the handle allowing you to loop your guyline around, and feed it down to the bottom of the snowstake. This guyline path allows for stronger holding by pulling on the bottom of the snow stake where the strongest, hardest snow will be encountered.
