Abstract: An ice auger has a rotatable rod adjacent and parallel to the central shaft supported at the bottom in a cylindrical receptacle. A vertical ice reaming blade is attached to the rod above the receptacle and a retaining loop affixed to the shaft and positioned above the blade prevents the rod from rising out of the receptacle. A right angled handle at the top of the rod extends outward above and in the same plane as the blade. A spring biased latch assembly disposed near the top of the shaft engages the handle with the blade in rest position. Releasing the latch frees the rod to rotate 180° and move the blade to use position extending outward beyond the standard auger members to ream the bottom of the ice hole. Vertical support posts stabilize the system and prevent wobble. One post functions as a stop and back support for the blade during use.
