Is knife weight a factor when you are buying a knife??? i can see it being a factor in a military or hiking were more poundage means more work... but personally i don't care that my ka-bar is heavy and bulky, but its bullet proof when i need it and it gets it done... if there's a significant trade off for the extra weight I'm probly willing to do so...
I prefer a medium to larger knife for EDC, but during the summer if I'm just hanging out in a t-shirt and shorts on a hot day, I will go with a smaller knife. If I'm out camping or doing light hiking, I like a big heavy duty folder.
Weight is not an issue unless I am looking for a knife to fit a specific purpose. For EDC knives it really doesn't matter what that weight is but for hiking I want something as light as I can get without sacrificing performance.
I'm not to picky, the only thing is it can't be to heavy for my full loadout e.g. cell phone, multi-tool, keys, Wallet, notepad, pens and so forth.
I just want my EDC to be comfortable so if a knife weighs to much it better give me something that a lighter knife in my system can't!
As for hiking the same holds true, how much am I carrying and is it "good" or "bad" weight. In other words is the weight I'm carrying giving me more capabilities in the field to justify the extra weight.
