Abstract
A blade housing for an electronic cutting apparatus includes an outer housing having a distal end, an inner housing coupled to the inner housing and longitudinally selectively adjustable relative thereto and a blade rotatably coupled to the inner housing with a sharpened distal end. Adjustment of the inner housing relative to the outer housing adjusts an amount of the blade that protrudes from the distal end of the inner housing.
Claims18
A blade housing, comprising:
- an outer housing having a distal end;
- an inner housing coupled to said outer housing and longitudinally selectively adjustable relative thereto at a plurality of discrete set points;
- said inner housing includes a plurality of detents and further including a biased bearing coupled to said outer housing, whereby the bearing can be selectively engaged with one of said plurality of detents by rotating said inner housing relative to said outer housing
- a blade coupled to said inner housing and having a sharpened distal end;
- whereby adjustment of said inner housing relative to said outer housing adjusts an amount of the blade that protrudes from the distal end of the inner housing.

A blade retaining apparatus, comprising:
- a housing having a first end, a second end and a longitudinally extending bore therein;
- said housing comprises an inner housing and an outer housing, said inner housing is coupled to said outer housing and longitudinally selectively adjustable relative thereto
- and a cylindrical blade having a distal sharpened end rotatably coupled to said housing and at least partially positioned within said longitudinally extending bore such that at least a portion of said distal sharpened end protrudes from said second end of said housing;
- wherein said inner housing is adjustable relative to said outer housing at a plurality of discrete set points to adjust an amount of the blade that protrudes from the distal end of the inner housing and said inner housing includes a plurality of detents and further including a biased bearing coupled to said outer housing, whereby the bearing can be selectively engaged with one of said plurality of detents by rotating said inner housing relative to said outer housing
- said second end of said housing defining a relatively flat surface around said at least a portion of said distal sharpened end of said blade.
