Hand knife with integrated miter guide

A hand knife with an integrated miter guide, suitable for cutting a workpiece such as a thermal pipe insulation, comprising:

• a longitudinally elongated knife blade, the knife blade being substantially planar and comprising a first face, a second face opposite from the first face, a longitudinal cutting edge at a contiguous edge of the first face and the second face, and a blade back substantially opposite of the cutting edge, a blade distal section, a blade middle section adjacent to the blade distal section, a blade proximal section adjacent to the blade middle section, and a blade proximal end extending from the blade proximal section being suitable to be attached to a handle,
• wherein the longitudinal cutting edge comprises a cutting edge distal section, a cutting edge middle section adjacent to the cutting edge distal section, and a cutting edge proximal section adjacent to the cutting edge middle section, wherein the cutting edge middle section defines a substantially straight line, and wherein
• a transverse axis is defined perpendicular to the cutting edge middle section and bisecting the first face and second face;
• and
• a plurality of alignment markings disposed on the knife blade configured at an angle between 45-degrees and 0-degrees, inclusive, relative to the transverse axis, wherein each from the plurality of alignment markings visually delineates a line substantially across the knife blade between the cutting edge and the blade back, inclusive, wherein at least one from the plurality of alignment markings is configured at 45-degrees on the first face;
• and
• further comprising indicia disposed on the knife blade indicating angle values corresponding to the plurality of alignment markings;
• wherein the cutting edge middle section lays across the workpiece at a congruent angle to that formed by the alignment markings and the transverse axis.
