Roller cutter with retractable and removable cutter wheel

Image Number 3 for United States Patent #6438850.

A roller cutter has a partially circular housing having a slit extending in from receiving a cutter wheel, which can be selectively shifted between an extended cutting position and a retracted position enclosed within the housing to protect the cutter wheel cutting edge. A push button operates a latch release to allow shifting between these positions. A slide bar mounting the cutting wheel for shifting movement is itself held in a slot in the housing, but may be released for removal and cleaning. A tangential grip at the top of housing allows convenient stroking for cutting pizza, mincing herbs, etc.
