Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
204 words
A cutting tool comprising an elongated vertically standing body member having oppositely disposed ends with an upstanding handle portion on one of its ends and having an upwardly extending semi-circular cutaway area therein inwardly of the other of its ends communicating with a slot extending toward said other end so that a first part of said body member lies below the semi-circular cutaway area and the slot and a second part thereof lies above the semi-circular cutaway area and the slot, a pair of spaced circular cutting blades, means for mounting said pair of circular cutting blades on said first part with one blade on either side of said first part with their upper peripheral edges in said semi-circular cutaway area, a single circular cutting blade, secondary means on said second part mounting said single circular cutting blade in said semi-circular cutaway area with the lower peripheral edges of said single circular cutting blade engaging the uppermost peripheral edges of said pair of circular cutting blades whereby movement of said cutting tool along the upper surface of a work piece to be cut causes said circular cutting blades to form a double cut line in said work piece by separating a narrow strip therefrom.

A cutting tool comprising an elongated vertically standing body member having oppositely disposed ends with an upstanding handle portion on one of its ends and having an upwardly extending semi-circular cutaway area therein inwardly of the other of its ends communicating with a slot extending toward said other end so that a first part of said body member lies below the semi-circular cutaway area and the slot and a second part thereof lies above the semi-circular cutaway area and the slot, a pair of spaced circular cutting blades, means for mounting said pair of circular cutting blades on said first part with one blade on either side of said first part with their upper peripheral edges in said semi-circular cutaway area, a single circular cutting blade, secondary means on said second part mounting said single circular cutting blade in said semi-circular cutaway area with the lower peripheral edges of said single circular cutting blade engaging the uppermost peripheral edges of said pair of circular cutting blades whereby movement of said cutting tool along the upper surface of a work piece to be cut causes said circular cutting blades to form a double cut line in said work piece by separating a narrow strip therefrom.
Claim 3
Dependent Claim
55 words
The cutting tool combination set forth in claim 1 and wherein said secondary means mounting the single circular cutting blade consists of a pair of support arms attached to the opposite sides of said vertically standing body member and a pin positioned in apertures in said support arms and journaling said single circular cutting blade.
Claim 4
Dependent Claim
40 words
The cutting tool combination set forth in claim 1 and wherein said slot is angularly positioned with respect to the axis of the elongated body member so as to extend downwardly into said first part to form an angular guide.
Claim 5
Dependent Claim
26 words
The cutting tool combination set forth in claim 3 and wherein the end of said slot is enlarged and the enlarged end wall thereof is tapered.
