The button
I bought this knife two weeks ago. I have bought alot more knives from this company and never had a problem with them. I love this knife it's one of my favorites, I have arthritis in my right hand and the button to open it is so hard for me to push to open it up I just can't do it. It's really isn't any good for me! I'm really bummed out! I really love this knife! Ralph s,
