kindling-log chopping is better. Sharpness -probably a bit sharper than a hatchet but not much.
Here is the trick.
Without too much force, strike the log so that the axe enters the log firmly. Don’t try to do a single chop(ok sometimes it happens because you catch the sweet spot). But assume you don’t and it just wedges firmly into the log.
Then lift the entire axe and log together and then bring it down on to the chopping block so that the top of the axe strikes the chopping block first.
This move requires a turning movement which becomes remarkably easy with a bit of practice
Result: log splits nicely-usually.Repeat if it is a teuch bugger.
Would the same trick work for a hatchet and kindling?
