The CIVIVI Cogent button lock knife is the perfect folder for those looking for easy one-handed operation. The knife features top-end flipper action; an alternate method for opening is simply pushing down the lock and flicking your wrist. A similar action will close the knife, no off-hand needed. It comes at a killer price point to deliver value for years. If that's not cogent grounds for purchase, then we don't know what is.
Had this knife for a few months now and I'm loving it. Great action and ergonomics. Love the blade size. Works great for slicing and dicing in the kitchen and gets the job done in the woods logging. I don't abuse it like I do my Barrage, but of course, it's not made for that. Very fidget-friendly after I took it apart to resolve the sight lock stick. I'm very pleased with my first Chinese knife, so much so I bought the Altus too. I like it so much I'm pretty sure I'll buy another one.
