After taking a look at the Rapid Warrior Utility Knife, I think you'll agree with me that Swiss Army knives are for wusses. I mean, the name says it all--warrior, and a rapid one at that. With these blades, you'll get the job done in record time.
Equipped with drywall, hacksaw, and general purpose saw blades, the Rapid Warrior Utility Knife offers a convenient tool that switches easily for whatever purpose you have. And it's only $20.
