Couteau pliant ANV Knives A400 BB - DLC Black Sleipner - G10, noir

I am very disappointed with how rough it is to open. It is impossible to open the blade with the back flip without using a sharp movement of the wrist. You can feel and even hear the friction when opening it. Lubricating the pivot did not change anything. The response from ANV customer service was surprising: "You are not the first customer to report this problem to us. And there is a solution... Thanks to the DLC coating, the locking bar softens after a few openings, which is normal. Can you check for me if, when the knife is closed, the blade does not touch the handle on either side? " I've probably opened this knife more than 100 times, and I've only noticed a slight improvement. This type of quality really doesn't suit me. I sent it back to Lamnia. Lamnia handled this case with a real focus on customer satisfaction. I thank them for that. I will continue to be a customer of Lamnia, but probably with ANV.
