I have Buck folding knife. I love it, but is really tough to open?

It's how it's made. So it stay open when using it. It is solid made tight . Made to last a lifetime. But if you want it to open easier you can oil it . That helps. Or you can take it apart adjust it . But what I do is oil it with grease lubrication from stray can. It like wd40 but better. Open and close it a lot and that should help make it easier to open. Usually buck knifes have lifetime warranty so if want to keep the warranty do not take it apart. . Hope that was the type of answer to the question you were asking. Wasn't sure what you were asking.
