EDC'd emerson qcq-14 for 2 years and then switched to ZT 301 for the last year.
no lock-up problems on the emerson,i just got lucky.there is side to side blade play on the emerson while there is absolutely zero blade play on the 301 and of coarse with the frame lock there is no lock-up probs. with the 301.
i had to re-grind the edge on the cqc-14 because i dont like the chisel grind.now its good.
the 301's only down fall is size and weight.other than that its one hell of a knife.biggest & baddest folder i've ever held.
the only good thing about the emerson is its small and light and the WAVE feature is good if you really intend on having it for self defense,other than that its annoying and a hindrance since it opens everytime you remove it from your pocket.
i would go with a spyderco or benchmade before an emerson.they have way to many lock-up problems for a knife thats supposed to be "tactical" and way to much blade play for a $200 knife with a chisel grind.
i ditched the 301 for a strider.it has everything that the 301 has but is a more manageable size and weight.
i like the 2.7in blade on the qcq-14 for the times i need to be PC or somewhere with 3in blade restrictions but other than that i'm done with emerson folders,not impressed at all,and for $200:thumbdn:
