This idea came to me clearly around a month ago, after the day I've been thinking about Gabe Newell's love to a knives.
The plot and the basics of this idea are very simple, many of us knows that all of this years knives had some religious kind of meaning to most CS:GO players. Since Counter-Strike 1.6 was released, it became a very popular thing to play rounds only with knives. And all of this years, making frags with a cool knife was a piece of aesthetics for many of players(us).
I’ve decided to turn this idea into a randomized pattern. But when I finished drawing knives I was still unsatisfied with this stylization...
Some people on the workshop know that I love to bring my own touch and life experience to my designs, and it's the most important thing for me to leave a piece of my imagination and to make player empathize the atmosphere while playing with my design. So I’ve worked more on the stylization of these knives and turned this idea into something that I would really enjoy as an artwork.
Butterflies are my favourite insects. "Butterfly Effect" movie is in the top of my list of movies. And I’m often thinking about how small change in anything can result a large difference in a later state of life.
DC comic’s character "Rorschach" is famous for his mask that was the key for my connection with knives and butterfly’s. The symmetry was the answer.

Remember, knife is a button 3 on the keyboard~

I thought that uploading 9 versions of every weapon, is not a good idea. It really seems to be just a spam over the workshop. So I’ve uploaded screenshots with the other variations, in case of your request.
