I recently picked up a Kershaw 6034 Emerson Designed CQC-6K Knife from Amazon.
The Kershaw version of the Emerson knife has both a disk for opening and the wave feature that can help open the blade as you remove it from your pants pocket.
Priced at $21.95 and free shipping its one heckuva nice knife at a great price.
So, is it sharp? Yes, yes it is.
On arrival the plastic casing was starting to get beat open from the blade hitting it during shipping.
How sharp is it? The wave feature is quite neat, but if you open it along with a backwards movement form your pocket, and don't fully clear it away from your side, well...let's say the knife is so sharp I had no clue this had happened at the time and only noticed it afterward:
Ah, It was time to retire that old pair of jeans anyways....
The lock on it is nice and solid and it fits the hand very well and the grip shape and texture keeps it steady in your hand for all tasks that may require a pocketknife. I'm quite pleased with the purchase.
