Hand -held can openers are manual kitchen tools designed to safely and efficiently open food cans. Consisting of a cutting wheel and a handle, they work by rotating the cutting wheel around the can's edge to create a lid-removal groove. The user turns the handle, causing the cutting wheel to puncture the can's lid while rolling along its edge. This action cleanly separates the lid from the can's body, enabling easy access to the contents. Hand -held can openers are compact, portable, and don't require electricity. They are a staple in kitchens for quickly accessing canned goods without the need for more elaborate electric can openers.
