This style of chopping is considered easier to master than the standing block.  The log lies horizontally in a cradle and is fixed or “dogged” at one end so that when the log is severed, the free end falls away.  Axemen place “foot holes” in the blocks to give then a safe flat platform to stand on.  Although the axeman actually cuts the scarf between his feet with a razor sharp axe, it is much safer than it looks.
