Well, I took the plunge and bought a Fiskar brush hook from B&Q today. They don’t look nearly as scary in reality as they do in the pictures; it’s more handle than blade and it’s not particularly sharp so I’ve got no qualms about carrying it in my pack. It’s clearly a tool not a weapon. It’s also assuaged my fears that I might cut my own leg off or something! I quickly found the best way to swing it was a sideways swiping motion rather than chopping like an axe which makes it safer too as you’re always swinging it away from you.
Even though it’s not that sharp it does go through ferns, nettles and brambles up to about 1/2″ like butter which is exactly what I wanted. It happily goes through thicker branches too with a few chops but I would definitely get a pruning saw if I were going to do that often.
Spent just over an hour this evening clearing a totally overgrown trail – quite enjoyed it actually! (Except for the fact that I’d forgotten my Jungle Formula so got eaten alive by biters!) Had a good sense of accomplishment afterwards when I rode the cleared trail. Already know which one I’m going to clear next!
The only problems with the Fiskar are the crappy “sheath” and the fact it’s quite big because of the long handle (doesn’t quite fit in my pack). Kind of wish I’d gone for the Silky Yoki which has a proper sheath and is quite a bit shorter. It’s over twice the price though and would have been a lot of money to splash out not really knowing anything about that sort of tool.
@z1ppy – B&Q also had a folding scythe, IIRC exactly like the one in your eBay link but a different colour and cheaper (around £15). Looked a bit shoddy quality-wise but will no doubt do the job.
