I sooner try to drain the ocean with a teaspoon than quarter an elk with a Swiss Army Knife. Just the thought of it raises blisters on my thumbs. Truly the embodiment of the saying "where there's a will there's a way".
I would be de-boneing.
I took apart my last 2 moose with a Havalon piranta, what are those? 2.5 inch blades maybe.....when you know how, you learn a big knife is generally more of a PITA than a small one...
Used to clean about 300 deer a year on a ranch we guided on, mostly with a 2 inch blade...
