The plane is supplied with a 3.5mm thick, 50mm (2 inch) wide plane blade, hardened and tempered to 60-62 Rockwell C along with a finely machined chipbreaker and cap iron, all of which help to significantly eliminate the risk of chatter.

The plane blade is controlled with a Norris style adjuster. The single adjuster can be used to make accurate lateral blade adjustments or blade depth adjustments. The adjustments are controlled using the knurled brass nut located above the blade.

The lateral adjustments are made by moving the adjuster sideways which in turn moves the blade laterally. The depth adjustments are made by turning the knurled brass nut which in turn moves the blade towards or away from the mouth.

Note: ensure to release the lever cap before making blade adjustments to avoid damage.

The frog is the central part of the plane on which the blade rests and where the blade adjuster operates. The frog also has the functionality of being able to adjust the mouth thickness at which the shavings pass through.

The Kunz Plus 4 plane is fitted with a shapely rear handle and an extra bulbous front knob, both of which are made from Cherry.

The top side of the body is finished with a dark green finish.

The plane is supplied in a Kunz cardboard box.
