The edge

Like begets like, money begets honey, life begets ...

Touch me and then thy shall know, thy shall realize how much I love you and how much I care for you. You make me do the dirty work, you have made me into a butcher much like the Abdulla, the butcher in the WWE. You should know it very clearly that the bloodshed I have done is because of you. They blame me for all the heroism that I have done. 'Heroism' might not be the original word for it. It may be 'Shrewdness'. You have made my edge a synonym for the terror. Earlier, the rogues have created a bad name for it. Although, the Sikhs had tried to build my reputation they gave me the status of the religious symbol. They must better watch out who try to use me unconventionally.

My invention

I was surely invented for the daily work and not for bloodshed. You people have done all the flesh cutting with it. Earlier I was the part of a rock. Then the rock fell down and some people found me useful and I was born, Ya, this is the truth and don't believe in the fact that some intelligent man found a small rock and so he decided to rub me against another in an attempt to get fire, that's a cooked up story. The race of humans love fascination and they tend to twist and turn and make simple things so much complicated that even they are confused about what they have been doing so they end up making things simple again.
It will be better if the rest of the story is kept as a secret.

Development

Ya, the machine of malice were right when they said that I was furthered developed just to cut human bodies and then help them reach to the hell as early as possible. The teeth were added later on and slowly and slowly the inches got reduced to cms and as the technology progressed, the cms got converted into the mms and now mmms. Hmm, the full forms must be clear to you if you really deserve so.
The Japanese made it popular, the katana, and the rest just followed. None put in efforts to develop the so-called small knife, everyone, as I have earlier mentioned were interested in making things more and more blood smearing rather than cutting vegetables.

Some extremities

The digital world took to the ultimate levels, it introduced the sport of fencing and the blades were made of glory and nothing else. They were so thin that even it couldn't stand without trembling in the air, they just stood and nothing else followed. It is so weak and fragile but technically the sharpest thing, even a mere touch of it dangerous, obviously, blood smearing is sure to happen at a larger distance. I am talking about my younger cousin, the saber.

The enemies

The gun was the most powerful enemy of mine, it has almost made me obsolete and I am an object of least respect unless it is hurled at you, but I am grateful to the Chinese to make me accessible to the poorest of the poor.

Thanks, that was my 500 on materialism...   Grateful to you forever, that was a knife...
