Vintage Pacific Handy Cutter PHC Box Cutter Costa Mesa California, New in Box. Made in the USA. Ships free with USPS ground advantage. Adjustable-blade safety knife with carton-cutting guide Will not work with standard blades found in most box cutters. The PHC blade is the one on the bottom and has to lock in the the first upper notch. The upper blade is the standard one and it won’t fit as I have tried. Replacement blades can be purchased through PHC (Pacific Handy Cutter) website. Dec 4, 1986 - Pacific Handy Cutter, Inc. An improved, adjustable-blade safety knife of the type having a replaceable, single-edge blade slidably-retained within a single-piece handle against a keeper plate having a tang to engage the blade in a side-by-side assembly for protraction and retraction out of one end of the handle has planar guide member extending forward from the cutting end at one side of the knife at a controlled distance from the blade when the blade is extended and at a slight angle relative to the blade such that, when the face of the guide is brought into contact with the surface of a cardboard container, the blade is constrained to cut the side of the carton at a slightly inclined angle from the horizontal and along a line whose spacing from the container top is closely controlled, thereby preventing injury to the container's contents. A U-shaped retainer clip is disclosed which is slidably-retained in the rear of the handle and cooperates with a laterally-extending pin at about the middle of the handle to define a spare-blade-receiving space within the handle within which a plurality of spare blades may be safely stored for future use.
