another thing to keep in mind is the type of screw for example when i make a folder i use flat head screws on the inside stuff so they sit flus with the liners on the outside i use either button head or socket head because you have more room to recess them....how much is this knife worth to you? check your private messages i have a idea that mght help you determine what type you need OH yeh your going to need a pivot as well and a stop pin
