Talk:Folding Blade/@comment-43614028-20200629173432/@comment-46158069-20200701131520

I had an idea for a similar blade, it'd operate via a recessed button in the handle that can be pressed easily but not accidentally, this button activates a powerful magnet that causes the telescopic blade to shoot up, and pressing again inverts the polarity somehow, that casing would have to be something that insulates the magnetism. Just a little musing.
