Well, I thought I'd quenched my thirst for BIG knives, but apparently NOT! I have been watching all 4 of these knives for quite sometime, but was afraid to order ANY of them due to their "assisted" features, because they would have been seized by Customs. But I found a Canadian site that had them in stock, and that meant no borders to clear, so...! First up is a CRKT "Flat Out" that is 8" oal/SS drop/needle-point blade with dual-studs, all SS body fastened with screws, adjustable pivot, frame-lock closing, and a pocket-clip. It has a weight of about 5 oz.'s, and came shaving sharp. This knife features the CRKT patented "Outburst" assisted opening system, which I found to be the undoubtedly fastest opening system I've come across short of a switchblade. With just a slight nudge on the stud the system takes over and springs the blade open incredibly fast. If I had a complaint about this knife it would be the frame-lock closing as I much prefer a linerlock. I find the frame-lock takes a lot away from the look of the knife, but I can live with it. I just love the smooth clean profile on this knife. Second is a Cold Steel 13 1/2" oal "Luzon" linerlock/8Cr13MoV clip-point blade with pull/fuller dual-flippers and dual-studs, accented ZY-EX covers, adjustable pivot, linerlock safety slide, and more-or-less integrated pocket-clip. The weight is 9.3 oz.'s, and came razor-sharp, just like all C/S knives. The slide safety I mentioned is a notched slide on the back cover that when engaged prevents the liner-lock from operating, and the integrated clip is also made of ZY-EX and blends right in to the back cover, so much so that I didn't actually see it at first. This is one of very few knives that I will leave the clip on because it blends in so well. Third up is a C/S 13 1/8" oal "Counter Point XL" mid-lock that C/S has named the "Tri-Ad" lock, AUS 10A bayonet blade with dual-studs, ZY-EX covers with through holes, adjustable pivot, and pocket-clip but this one I took off. About the same weight of 8 oz.'s, and a blade so sharp I cut myself quite badly the 1st time I closed it. The mid-lock was quite tight so I had to use two hands to push it down, and when the heavy blade disengaged it drop onto my knuckle and sliced right into it. Took me 20 minutes to control the bleeding! Won't be doin' that again any time soon, duh! And last but not least is a C/S 13" oal "Ti-Lite" linerlock/AUS 8A bayonet blade with single stud and dual flippers, the same ZY-EX covers with holes, SS liners, adjustable pivot, and pocket-clip which once again was removed. This one is a bit lighter at about 7.5 oz.'s, and equally sharp but this time I didn't cut myself. All 4 knives walk and talk perfectly, and the fit n' finish is 2nd to none. If I were to actually carry and use any of these C/S monsters I would have left the clips on and clipped them to my belt, because to put one of these folders in a pocket would be totally intrusive. This pretty much completes my set of C/S monster folders, save for the large and extra large "Espada's", but since I don't much care for those I think I'm safe! Thanks for watching guys!
