I bought a Gransfors Small Forest in 2003, when they were £45. I wanted it for bow making. Prior to that, I had used a Draper Hand Axe from Homebase. After the Draper, the GB was a revelation. A couple of years on I bought a GB Mini. While the Mini is certainly cute, I have not found that I use it all that much. When I need to chop, the SFA is far more capable, and when I don't need to chop, I don't need the Mini.
I recently re-handled a slightly heavier Hult Bruks head on a longer handle than the SFA. Its okay, but I still find I like the SFA better. Size-wise, if you are to have only one axe, I think it is impossible to beat the SFA package; long enough to get both hands on and give a good swing for felling trees up to 8", and not so long that you cannot choke up for craft work. It is not the ideal for either task, but it will do both.
The problem for someone asking advice is that all advice relates to the use that particular person puts their tool to. What they are doing and where.
I don't use my SFA every day, or even every week. I have a HB splitting axe to feed my stove, which gets more regular work. The GB gets used when I am asked to help with woodland management, tree clearing/limbing, when I have had spoon carving or bow making to do, or when I have been canoeing with a group in Scandinavia and we have been cooking on fires and have needed split wood. When I am solo camping, I rarely bother with a fire and if I use a hobo stove a knife, or the Mini is adequate. The Mini is not heavy enough to choose as a carving tools.
