My knife is my weapon 
It controls my actions  
It shows my way 
And it dictates my expressions 
The edge is sharp 
And painful to the touch 
But still I cannot perdict 
How it hurts so much 
For some reson it rarely hurts me  
But it hurts so much to others  
When I wheeled for all to see  
Everyone else it bothers 
Mostly sheathed it stays  
To harm no soul 
However when stowed one person it hurts 
For he pays the heaviest toll 
For i wish this weapon 
Could be turned to something useful 
So when its expressed to others  
It is considered good not harmful
