A multi-functional exacting knife assembly comprising:
- a) a knife body including a knife part and a handle part, the handle part extending at an obtuse angle from the knife part, a top of the knife part having an upwardly opening trough therein, a tube trough in the knife part opening through an end of the knife part;
- b) a trough case mounted in the knife part and extending outwardly from the end of the knife part;
- c) a cutting blade movably located in the trough case;
- d) a blade holding structure including a base slidably located in the trough case and connected to the cutting blade, a holding bolt attached to the base and extending exteriorly of the knife body, whereby movement of the holding bolt relative to the knife body moves the cutting blade relative to the trough case;
- e) a guide wheel attached to a bottom of the knife part;
- f) an adjusting wheel rotatably connected to the knife part and located in the upwardly opening trough;
- and,
- g) an adjustable blade guide support including a guiding support with a prop to adjust a depth of cut of a cutting edge of the cutting blade, an adjusting bolt extending from the guiding support and axially slidably mounted in the tube trough of the knife part, the adjusting bolt connected to the adjusting wheel whereby rotation of the adjusting wheel moves the adjusting bolt and the guiding support relative to the knife body.
