A tool accessory includes a first portion defining a drive end and a second portion defining a working end. At least one flat or planar side surface is defined on the first portion, and a tipping point is disposed between the first portion and the second portion. The tool accessory has a center of mass that is defined closer to the drive end than to the working end such that, when the tool accessory is rested on a surface, the center of mass causes the tool accessory to rest on the planar side surface and the tipping point to prevent rolling. The tool accessory may be included in a tool kit including a container and a tool including a handle and a tool head. The container includes a first portion having a first retainer that supports the tool, a second portion, and a middle portion that divides the first portion and the second portion. The middle portion includes a second retainer that supports the tool accessory. The container is configured to be stored in an upright position in which the middle portion supports the container on a surface.
