In order to adjust the screws on your knife, or to install replacement pocket clips or screws, you will need a Torx Bit set. These will vary in sizes, but you will need to select a set that includes a #6, #8, and a #10.
#6 Torx: handle screws, thumb studs and pocket clip screws
#8 Torx: Bali song Pivot screws
#10 Torx: Folder pivot screws
Please note: if you have any thread tightener such as blue Loctite, feel free to use a drop of that on the bottom thread of the screws; that will help them to stay in place.
