Handful of Concepts - Designers Knife.

"A swiss army knife created for designers."

I was thinking the other day, seeing as I quite like to have my utensils for working around me and knowing where they all are. Taking the idea of a Swiss Army Knife where all the essential equipment you need for camping / exploring is - you could create a "Designers Knife" with essential equipment needed for any area of design, for example the knife could include;

Pencil, Pen, Paint Brush, Ruler, Compass, Scalpel, Sharpener, Rubber ect.
