I've been carrying my 580 Barrage a lot lately. Was my first good knife about 8 years ago, I didn't carry it much for a long time. Recently I learned to sharpen and took the edge to 34degrees inclusive and gave it a good polish. Now its a great cutter and I remember why I liked it so much when I first got it. Carries small in the pocket for its size, axis assist is easy one hand open and close and the 154CM is great to sharpen.
