Forum noob here, trying out the "merit badge functionality"
I've used this Gransfors Bruks small splitting axe for about 3 seasons, mostly to process wood for the small Morso during winter.
It is excellent, especially for splitting our local knotty Hardwoods (with a captical H), like bluegum/eucalyptus etc.
It is big enough to split bigger sections (and small enough for kindling). These were already split in 2 or 3.
For scale:
GB Compared to a cheap hardware store axe. I much prefer the GB, it is as capable in terms of splitting capacity as the much larger and heavier (1800g) Grip axe, but much less tiring.
