This is a robust full-size knife and I'm glad I got it, but it comes with a couple of caveats IMHO. It came with a very sharp factory edge and despite it having the typically thick Twosun blade stock, the tall flat grind makes it a decent slicer. My copy needed a little adjustment on the lock bar tension and it now has decent action. It has a couple of flaws that warrant only 4-stars: The detent ball contacts the blade a little late so you have to move your thumb down to get out of the way of the flipper tab. The flipper tab is angled backward just a little too much so when the knife is open the flipper tab jimping (which is great for opening) is a bit rough on the finger when gripping the knife. You can contact the blade in the closed position (Twosun, that is a big no-no, come on...). Overall I was still happy to pick one up with WMK's recent sale on Twosuns, and add it to the collection.
