How you open an XM-18 is up to you, roll it or flick it open with the thumbstud, use flipper if it has one, inertia, there are lots of options for getting the blade out of the frame. Are they all perfect for everyone, nope. From ergonomics, to hardware strength, solid lock up, plenty of custom upgrade options, great cutters, the XM series have a lot to offer, but that certainly does not mean we can please everyone. That's why the knife industry has thousands and thousands of models to chose from, from $5 - $50,000, every style, lock mechanism, flipper and non-flipper, traditional to tactical, simple to technological marvels. Rick designs and builds knives with every intention of making the best possible product he can, but it is impossible to please everyone's personal preferences, but with thousands of XM's out there since 2005 I think we have a pretty good track record of happy customers, and high quality knives. If you are looking for a great utility/tactical knife for a wide range of cutting chores that won't let you down, we have the knife for you, if you are looking for the best "flipper" out there, we may not satisfy your need.
It looks like by post #11 the OP has worked things out, thanks for all of the feedback.
