Well I can't say anything bad about a Buck model 110 because I sort of cut my teeth on Buck, Kabar and Queen knives before I met up with the Great Spyder Factory
But to me Spyderco has many superb folders that are well suited for rugged outdoor cutting jobs. The Military for instance is about a rugged of an outdoor knife as you can get. I do prefer the ones with the exotic steels myself>> my Mili has that XHP steel and I'm very satisfied with it.
My current EDC is a Spyderco C-60 Massad Ayoob model>> it is the newer Sprint Run they did a year or so ago with the updated G-10 handle. I've taken it everywhere with me and have never been disappointed.
I was thinking the other day that this current Sprint Run we've been blessed with is a winner in that category as well>> I'm talking about the C-54 big Calypso that they just released here about a month ago. I haven't gotten one yet but it's super high on my list.
Some of Spyderco's fixed blades I love for the outdoors are my older Temperance 1 model ( PE & SE) and the new Southfork.
There really wouldn't be anything wrong with having a couple of Endura models for outdoor jobs>> I would want a pair of them though and to have one in PE and one in full Spyderedge.
If you could find an older Chinook III model that would also be a cool outdoor folder.
