You may not know this but it has been dated as far back as the late 1800s? These were among the great inventions of the past. It is called the Swiss Army knife. And it has been used by soldiers during the world war two. They used in opening canned food and is used to assemble rifles. The knife has had several revisions after that, putting in more tools that were useful for more people.

It gained popularity after that. And it has been used by a lot of people ever since. A lot of things that were deemed useful and very important during the past have somehow become obsolete these days. Because of the latest technological advancements, many ‘indispensable’ things are now unused. But the swiss army knife has endured all the latest advancements. It is still as useful as it was in the 1800s.
