My riding buddy from Telluride, Tom Thomas, has one of these attached to his handlebars.
He’s also got a killer backpack frame made up that carries a short bar Stihl chainsaw, but he says this handsaw is more useful.
Tom told me that after decades of trying everything out there the CO rangers, hotshots, etc. are all carrying this saw.
I have since purchased one, but haven’t had the opportunity to test it yet.
