If you've got a chubby for big knives, then good for you. If you feel the need to spend hundreds on a custom copy of the tool you need to make cups of tea and eat ration packs in the woods, then bravo to you!
I'll stick to be a little more practical with my money though. And as much as I carry a metaphorical anorack for good tools, I kind of don't for big knives.. Never have, and the more yanks I see play Rambo the less I will!
Mine was a gift and the parter knife sold for £55.
If you think an esee looks and acts anything like a "Rambo" knife then you know very little about cutlery, blade geometry, toughness, tang design ad ergonomics
I own many knives as well as make my own (and yes, I've even sold a few) in all different shapes and sizes for a number of jobs, but if I can only take one to the wilds my esee style camp knife is my go to, my scandi ground woodlore clone only gets a lookin when I'm carving. For general camp duties and hunting ( I hunt too incidentally) I always reach for the bigger knife.
I'm not saying there are not alternatives, this is just what I use and what I would recommend if I only had one to use.
Copies or second hand versions can be picked up within the price range specified so it's a valid recommendation.
I never use ration pals incidentally, I've always been of the opinion that if you can eat good food then why not.
Last trip out was Sri-Lankan style goose curry, slow cooked over a long fire and tasty it was too!
