The Invisible Blade

The cut is cleanly made,

When one uses the correct blade. 

But if the sword is misused,

Then chaos may then ensue. 

The blow is full of force,

When the blade follows its course.

Those who flail the knife,

Will not get to strike twice.

The blade has no shape,

But can deliver more than just a scrape. 

It harms with a poison one cannot see,

Delivered by just you or me. 

Words are the strength we all hold,

But some who use them may be more bold.

Think before you speak,

You don't know what you hurt when you can't see the wound.
