I was wondering what a good carry knife is at a reasonalbe price? I've seen a kershaw and some gerbers at my local walmart that appeared to be very well made knives.,are these good quality knives suited for defensive use? I'am looking for an assited opers or an auto opener or good quality. Last thing is when I say reasonable I mean maybe the $50-$100+ price range. Can I get a good tactical folder at this price?,I don't want to spend $450 for a knife but do I have to get a good quality folder? thanks
