I agree completely, the DF G10 has become a companion of mine, always have it on me and I have never come across a situation where the DF could not perform well
By the way, "Folding knife" and "Heavy Use" don't really go well together, if you must..get a Zero Tolerance, Emerson, Spyderco and Benchmade has some rugged ones too. The perfect 'team' for me personally is a DF G10 and a Manix 2.
I suggest you buy one folding knife for EDC and one knife, fixed blade preferably for outdoor and "heavy" use, don't try to use one knife for everything
