Hi! My name is Dima. I live in Russia, Moscow. I am a math teacher at the school. The pattern I have chosen for my design shows the letters of Roman and Russian alphabets from the one side, and the different triangles are shown on another side of the knife. The patterns looks like the chalk inscription on blackboard. First of all I think that it should remind people about their school time. From the other hand it pays attention to the significant role of the good school education for everyone.
