After years of carrying not-so-good folders, I decided recently to get a Benchmade Griptilian, since they seem to be very well thought of. I found a good used one and I've been very happy with it. Then I got a Zero Tolerance 350. It really opens up with a SNAP!, whereas with the Griptilian I have to flick it to open it. So what I'm wondering is, isn't the Griptilian supposed to have an assisted opening feature as well? If it is, mine doesn't seem to work. The knife didn't come with any paperwork so I don't really know any technical details about it, and I don't personally know anyone else who has one. Can anyone shed some light on this for me? Thanks!
