For reasons still unknown to me, I decided I'd try one of these and duly took delivery of a long-handled version. I've been trying it out for a little while now and thought I'd offer my observations.
Yes, it is a peculiar-looking tool when compared with many/most other options in the field but don't let that put you off! I use my axe mainly for splitting wood and preparing material for the fire when I'm out and about and this fulfils that role to perfection. The head is light, when compared with others, but I have found that it is much less tiring to use as a result. It splits wood easily, despite this lack of weight and the comparative shortness of the handle but this last quality makes it easy to pack and carry, too. When used with a mallet, predictably, the blade symmetry allows it to perform brilliantly.
It is perfectly good at limbing trees where the short(-ish) handle makes it a very manoeuvreable tool. With a little practice, is adept at felling as well, though it is not perhaps in the same league as those axes dedicated to that activity. When choked up and challenged with some modest carving or feathering chores, it is competent but no better than that, although it is very comfortable 'in hand'; however, it reminds me why I carry a knife as well!
Have I regretted my purchase? Absolutely not. For my purposes, it ticks all the boxes. It is very well-made to boot, with a particularly pleasing mask. It is an easy, unobtrusive carry that, for me, is now my go-to chopping implement of choice for any of my exploits in the woods. If splitting is the principal use to which you put your axe, then I would recommend the Roselli long-handled axe without reservation.
These are my personal reflections on my experience with this tool. I have no connection with the company (who supplied me directly) and, lest we forget, other axe manufacturers are available...
