Up here in Alaska, when you go out into the toolie-boons, you always take your pack - with whatever you might need if you get caught out longer than you anticipate. I've had a Trailmaster riding in my pack for over 20 years. These are fantastic knives, my favorite Cold Steel. Take a look at the thickness of the spine. I'm sure there is someone on the planet that could break one, but you would have to really work at it. The kraton handle is a real plus in the cold and absorbs the shock if you are cutting firewood or making a shelter. I haven't had any problems with rust, but I take care of my gear (a simple wipe down, Frog-Lube or whatever protectant when I get home). Can't say enough good about these knives.
