C-clamps, a rotary tool, solide work bench, also you'll probably want a saw manual or motor ran... Sandpaper and about 6 oto7 drawings before you even start.. Easier to screw up with a pencil and paper than to screw up on an expensive piece of g-10 or what ever material.tour gonna use... Measure twice, or more and cut once.... Sand to fit.. A Drill press is not mandatory, a vise or C-clamps will work, then a electric screw driver with cutting bits.... Also a caliper will be required to accurately measure the depth with scales on so you know how much to cut.... Are u gonna be getting new screws? If so than get them from spyderco. And if yer gonna use the same ones then it'll be a little Easter, measure the o.a length and what everyone else said, counter sink the holes..
