That axe looks to be too chunky in my opinion. The cheeks are too full and I would not be suprised if it binds in unseasoned wood. In dry wood it would do ok due to the wide and angle of the blade and the compression that would do to the wood but still would not be anywhere close to a well profiled axe. As a splitter it would do great, but for chopping, get a decent axe.
As for splitting wedges and hammering with the poll....
Metal wedges are a no-no. Luckily these days you can buy composite wedges made from ABS plastics that work fine and won't damage your axe. Failing that, use a wooden wedge. They are free, don't damage your axe and are easily replaceable.
Geoff: I would stick with the wildlife hatchet. It's a good size and a better axe in my opinion. Yes the Outdoor axe is lighter but it will take more effort for cutting due to the reduced efficiency from the wider bit. If you will be primarily chopping, get the WH.
