I've been using and carrying the new lawman for a few months now. Love it and the DLC is super awesome.
Even though it's a great knife it just feels different. I was reminded of how much more comfortable and solid feeling the old lawman is when i occasionally picked them up. Maybe it's just the muscle memory, since I've been carrying the old models since 2010.
But seriously try this, use the new thin lawman everyday for a week, then pick up the old one, your hand will tell you which one it prefers instantly.
