A manual wood splitter is one that operates without any sort of gas or electrical power. There are essentially three different types of manual log splitters. The first, one could argue, isn't really a wood splitter at all - it's just an axe.
Fire is one of man’s basic needs for survival and to keep the flame alive, firewood or fire log is needed. Splitting log or cutting wood is time consuming and tiring. It may result in muscle or back trauma and create risk of serious injury.
