Recently bought the above for moving large oak sections and have to say its an awesome bit of kit. I guess you'd call it a heavy duty cant or stockyard hook. Its built like Conan the Barbarian's battleaxe, very chunky thick gauge aluminium and steel, I'd say well worth the £100 odd. Got it from Rob (Alaskan Mills) on Ebay, excellent service as usual.
Surprising the size of log you can shift with it. Highly recommended for anyone with larger logs to manhandle.
