A former regular had gutted deer with a broadhead and a separate occasion a pen knife. Me, I like the havalons...blades are 2.75", I believe.
I started with the orange one super lightweight. Actually bought it off the bh.com shop. But I got a bit aggressive trying to split a rib cage and broke the blade stop pin out of the moulded plastic handle. It's a scary sharp scalpel. The scalpel blades snap easily if you try to pry or get into bone/joints. Slicing is aces. I usually get about an elk or a few deer out of a single blade, if I don't break the blade. I bought the Shockey edition (Grey) knife as it has a the rigid blade and replaceable blade scalpel. Down side bulk and weight.
