  • Wood splitter
    Patent number: 4033390
    Abstract: A wood splitting wedge is arranged on a vertical support such that the upper end of the wedge can be conveniently struck by a sledge hammer or the like in order to split a log provided immediately below the wedge and supported on a base which also serves to support the lower end of the support or standard. A second wedge is provided intermediate the first wedge and the standard and a handle serves to provide a convenient means for splitting small kindling with the second wedge. The second wedge serves the added function of spreading the sections of larger logs when they are being split in order to avoid jamming of the first wedge.
