I tend to prefer US axes Plumb, Norwoods, Kelly - all that - for their superior splitting geometry, and also a bit heavier than a hatchet - so 2 - 2 1/2 lbs head
But I have to say I do like that GB small splitting axe - had a swing of one a couple of weeks ago - pretty impressiveI'd kind of gorn orf GB because they aren't so hot at splitting
Splitting axe is a cracker. The only thing I could say about it was job done. Every time. No issues. Lol.
Ive got an unbranded axe which has a fat profile, put it on a 19" handle and it's brilliant.
All the best.
