Abstract: A log or piece of cord wood is supported upright on a base member between two support members which are secured to the base member so that at least one support member is movable toward and away from the other. The base member is sufficiently large to permit a user to stand thereon to positionally stabilize the base member while a log is being split. The support members are prevented from moving inadvertently during splitting by various alternative means such as of frictionally engaging one or both support members in tracks, spring biasing the support members toward one another, positionally locking a movable support member or by detenting the support members in various positions. The support members have concave surfaces extending at least 90.degree. around and sufficiently high so as to preclude movement of the log during splitting.
