Comfortable Knife

This knife is unique in that it let your thumb more comfortable when you pencil.

When we sketching, we usually do not use a pencil - sharpener pencil.
We use general knife more often .We often use the left thumb apply
direct pressure to the blade to use.Direct contact with the blade let
the thumb uncomfortable.That’s why we have such a design.
