I dug out my knife to make a comparison and found that it's not quite the same as the one in the photo. Very close, yes, but not identical. The blade markings are different, the grinds seem to be just a little different, the knife in the picture appears to have a slightly longer choil than mine, plus my knife's handle doesn't have that little lip at the end of the lock. Everything else looks to be the same, though. So, what knife do I have?
