i recomend the CRKT m16 or m21 the price is fairly good and the flipper is nice. the dual locking feature is also nice. they have lots of handle and blade options. they are the best i have used for under $75. there are more expencive models. i have a sog trident but it is not a real tough knife. my M21 is a beast. i will get another crkt or a emerson next but the ZT line of knives has got my attention.
