I love this knife. The only reason for 4 stars is that the blade is somewhat stiff out of the box and the pivot is so tight that is nearly impossible to loosen the pivot screws without possible damage. I'm a big knife guy and this one fits the billalmost perfect. A whole bunch of perfectly milled titanium with a gigantic m390 blade that'll punch through a car hood if needed??. If you haven't tried PMP knives, you should.
