Sometimes, you just need a small blade. One of those cases is in the outdoors, and when you go hiking or camping, you need a blade that is always with you for whatever you need (cutting rope or string, etc.). This Instructable aims to show you how I created a small blade (And attachable handle) out of stuff you (most likely) already have. Because I made mine out of a coin, I found that the soft metal as easy to dull, so its really a one time use. Even still, be careful where you bring it- Stay away from airports and schools with this, it could be considered a hidden blade. Please be careful if you choose to use it, as it is sharp and small. Concerns have been raised about whether it could be used for a weapon, and the answer is that it could be used as a knife, just like a knife would. However, using this to hurt someone is rather impractical, as it is so small. Not only should you avoid attacking someone in general, using this would result in you getting your teeth kicked in- there is no range. However, bear in mind that this is intended for educational purposes, and should not be used to hurt someone, either offensively or defensively. On the other hand, if you find you need to cut yourself out of a jam, such as a small rope that needs cutting, these can help.
I got the inspiration for this when i was talking to some friends about the coin necklace pendant I made, and you can see the 'ible for that Here
