Bottle openers are the handheld items that you never gave a major thought until the moment that you need to use these. This little kitchen or pocket tool has a long history and dates to the 1920s. These are so popular as these make opening the cans and bottle caps so easy. When you pull up using the one end of the same, the bottle opener pivots on the middle of the metal cap and this forces the lid off.
Often these are designed using stainless steel, cast iron or metal alloys and are attached to a solid wall as else it will not be of much use.
