Theta angle cutter is designed to cut up to 1/5 inch thick corrgate paper, foam board, rubber, or styrofoam in 30, 45, 60, 75, or 90 degree safely.  It is an excellent tool for architect modelings, science projects, and arts & crafts projects.  This is a must have an office product to protect from hand cuts.  It also can cut 20 sheets of paper in a single slice. 

In many offices, paper guillotines are used to cut multiple sheets of paper.  However, guillotine cutter is ugly, bulky, heavy, expensive and dangerous.  The retail price of a paper guillotine is very expensive: $50-100.  Theta angle cutter is a perfect replacement of a paper guillotine in any office.


Below is a website selling 45 degree angle cutter.  The competitor's angle cutter can cut only 45 degree angle.  The retail price is way more expensive: $69.99.
