Tree-felling wedge
The felling wedge is an approx. 30 cm long wooden wedge that is driven into
the saw cut when felling thick trees to prevent the saw from jamming and to
make the tree fall in the right direction. Usually two or three are used
together. These wedges can also prevent the saw from jamming when cutting
the felled tree into pieces. A splitting wedge is sometimes used instead of
the felling wedge. [MOT]
