## Abstract

Generally, a box opener system which provides in a single device a configuration to generate the open condition of numerous and varied types of boxes. Specifically, a cutter element in a handle disposed between a blade element and an impact element which can be used to disengage the sealed outer flaps or the side wall between perforations or cut box liners to generate the open condition of a box.

## Claims

### Claim 1

A box opener comprising:
a substantially rectangular elongate member having an elongate member first end and an elongate member second end, said substantially rectangular elongate member having an external surface having a portion of said external surface configured for grippable engagement by a hand of a person;
a substantially rectangular blade element having a blade first end connected to said elongate member first end, said blade element only connected to said elongate member first end, said blade element having a blade width substantially equal to a width of said substantially rectangular elongate member, said blade element having a longitudinal axis substantially collinear with a longitudinal axis of said elongate member, and said blade element having a tapered hebetated second end;
said elongate member second end defining an impact element;
a recess in said external surface of said elongate member between said blade element and said impact element;
a hold space inside said substantially rectangular elongate member, a portion of said hold space in communication with said recess;
a cutter element having a cutter edge, wherein said hold space holds said cutter element to recess an entirety of said cutter edge a distance below said external surface of said substantially rectangular elongate member and with a portion of said cutter edge in the portion of said hold space exposed within said recess to allow said cutting edge to perform a cutting function.

### Claim 2 (depends on 1)

The box opener of claim 1, wherein said recess has tapered sides which angle toward one another approaching said cutter edge of said cutter element.

### Claim 3 (depends on 1)

The box opener of claim 1, wherein said impact element tapers to a substantially rectangular end surface with a width that is smaller than said width of said substantially rectangular elongate member.

### Claim 4 (depends on 1)

The box opener of claim 1, further comprising a magnet attached to said external surface of said substantially rectangular elongate member.

### Claim 5 (depends on 1)

The box opener of claim 1, further comprising an aperture extending through said substantially rectangular elongate member.
