The seemingly inoffensive spoon can rip a lid from its can, but you need to wrap the handle in a cloth or towel or wear heavy gloves, as the technique takes its toll on your palms. Hold the spoon upright, steadying the tip of the handle with your thumb and gripping the shaft firmly. Rub the concave spoon end furiously against a small section of the inside lid until it breaks through. Once you have an opening, insert the spoon and nick at the can toward yourself, rather than away, until you complete a circle. For best results, use a heavy, thick spoon that won’t bend under pressure.
