## Abstract

A cutting apparatus for hair or fiber protruding from a surface includes a roller, a number of cutting features disposed at an outer peripheral surface of the roller, wherein the number of cutting features is adapted for cutting the hair or fiber when the roller rotates in contact with the filamentous surface or is moved while in contact with the filamentous surface.

## Claims

### Claim 1

A cutting apparatus for cutting filaments from a filamentous surface comprising:
a roller comprising,
a rigid body,
a compliant outer peripheral surface surrounding the rigid body,
a flexible cutting surface disposed at the outer peripheral surface, the cutting surface including a plurality of slots, and
a handle that supports the rigid body to permit free movement of the body; wherein each of the plurality of slots includes at least one of a protruding cutting edge and a pair of opposing cutting edges forming a sharp-edged aperture, the sharp-edged aperture being pressure activated to change shape from an open configuration to a closed configuration as the flexible cutting surface moves across the filamentous surface.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein the roller has a circular cross section.

### Claim 3 (depends on 1)

The apparatus of claim 1, wherein the opposing cutting edges engage a filamentous protrusion and sever the filamentous protrusion when in a closed configuration.

### Claim 4 (depends on 1)

The apparatus of claim 1, wherein the flexible cutting surface comprises one of a sharp-edged wire, metal or metallized material.

### Claim 5 (depends on 1)

The apparatus of claim 1, wherein the roller is a cylindrical roller supported for rotation on a first end of the handle about a longitudinal axis of the cylindrical roller.
