I have some tools that have three prongs, but the outlet I want to use has only two prongs. Can I safely cut the extra prong off?

No, the third prong is the grounding prong. If you cut it off or use a plug adapter that is not grounded, you will disable a feature that is designed to protect against electrical shock.
