Use a sharp knife to pierce a small hole near the rim, then cut around the rim to open the can
Use a butter knife or thin blade to carefully pry the lid up along the rim
Use a can opener-style tool made from a household item (e.g., a sturdy flathead screwdriver) to lift the lid edge
Use scissors to cut through the lid edge by working around the perimeter carefully
Use a spoon to pry up the lid by inserting the spoon between the lid and rim, working around
Tap the rim firmly against a hard surface to loosen the lid, then pry it open
Use a hammer to lightly tap around the rim (not the center), then lift the lid with a flat tool
Use a strong pair of pliers to grip the lid edge and pull it back after creating an opening
Heat the lid edge slightly (hot water or brief heat) to expand metal, then pry open with a flat tool
Use a survival-style method: puncture two holes (near opposite sides of the rim) and drink/pour from the gaps
If it’s safe and available, use a commercial “no-opener” can opener tool or multi-tool can opener
