No special tools needed for vinyl tiles/planks.. You literally just use a carpenter's knife (box cutter) and straight edge to "score" the wearing surface (surface you would step on) of the plank and then snap it in two like a KitKat bar along the scoring line.
Fancy corners and around door frames is more complicated, but the concept is still easy you just might need to cut through the entire product with the utility knife (6-7 cuts) instead of scoring/breaking.
