Ok, so some of you are probably backpackers or at least hikers. Which spydie would you recommend for this activity? The catch is that it should be lightweight as to not add a bunch of weight, folder, and also long enough to give some sense of protection (being false as it may be). This is what I am looking for in a knife. I dont have any stores near me, so everything I buy is usually just from the pics online. Thanks in advance!
