Straight-Going&Knife / Knife

Straight-Going&Knife
Straight-Going&Knife

For the sake of cutting a straight line without a ruler,we design a kinfe which can go straight by itself. This knife is attached in a tape inside,and we cut a groove on the middle of the tape so that knife-edge can insert in the groove accurately.
