Slide action wood splitter - GIF

[Toolmaker51]

Kinetics (?) of slide hammer is good competition for inertia (?) of axe. Way less physical effort than getting an axe overhead, probably more impact on joints though, axe mainly bears on wrists. Real speed of slide hammer in the wood bundled together, remaining upright. Slide hammer or axe not as effective when stuff falls over.

PJ's right though. Reaching into wallet for $30 bucks substantially easier...but not better at thin parting sizes between kindling and intermediate fuel. Quartered stumps don't light themselves.
