Comb identity and role Establish whether the object is a comb and which strand-handling roles its features support.

Toothed working structure

Identify the supported teeth and the path available for strands between them.

Comb structure test

Record the observed tooth structure and intended strand interaction as the basis for classification.

  2. What distinguishes this object from a brush, cutting tool or unrelated toothed component? boundary

Supported comb roles

Separate observed capabilities from named or advertised comb types.

Role evidence

Record whether the comb is intended for moving through strands, remaining in them or performing a specialised separation task.

  1. Which roles are supported by the tooth arrangement and body design? definition
  2. What marking, instruction or observed use supports each assigned role? provenance
Tooth geometry and engagement Describe the working gaps, reach and contact surfaces that govern engagement with strands.

Spacing and reach

Tooth zone dimensions

Locate zones with different gaps, lengths or orientations and preserve their measurements separately.

  1. What are the clear gaps and tooth lengths in each working zone? measurement
  2. Where do spacing, length or orientation change enough to require a separate zone? boundary

Tooth contact profile

Describe the surfaces that encounter strands and potentially the scalp or skin.

Tips, edges and roots

Record tip shape, edge finish and tooth-root transitions relevant to smooth passage and contact.

  1. What tip shapes, edge profiles and root transitions are present in each tooth zone? definition
  2. Where are seams, burrs or abrupt transitions that require closer inspection before use? action
Comb body and material behaviour Capture how the spine, grip and materials support controlled movement of the teeth.

Grip and force transfer

Identify how the user holds the comb and controls the working tooth zone.

Handling features

Record the usable grip, spine support and any tail or folding feature that changes handling.

Strand and task fit Assess this comb against the particular strands, contact context and intended result.

Target and zone selection

Relate tooth geometry to the target section and intended separation or arrangement.

Use context match

Record the intended strands and task, then identify the candidate working zone and evidence for its suitability.

  1. What strands, section thickness, tangle state and wetness will this comb encounter? definition

Pass and retention behaviour

Observe whether the comb performs its assigned role without unacceptable resistance or loss of control.

Use continuation decision

Record task-specific observations that justify continuing, adjusting or stopping a combing or retention action.

  1. During a permitted trial, does the comb pass through or remain positioned as intended, and where does it catch, slip or flex? measurement
  2. What observed resistance, discomfort, strand damage or instability requires stopping or changing the method? action
Tooth condition and reuse Determine whether damage or retained material prevents the comb from returning to its intended task.

Damage at working surfaces

Locate defects in teeth, tips and their supporting spine.

Working integrity decision

Record missing, bent, rough or fractured features and their effect on the usable tooth zones.

  1. Which teeth, tips or spine sections are damaged, and what change in geometry or finish is observable? measurement

What it is Filled

A comb is a rigid implement whose regularly spaced teeth project from a spine (back), used to separate, align, clean, hold or ornament hair, textile fibres or animal coats, with tooth pitch and stiffness determining the job.

In scope

  • Tooth arrangement, spacing, length, profile and tip condition
  • Spine, handle, grip and any integrated parting feature
  • Material, rigidity and response to the intended working environment
  • Compatibility with the intended strands, wearer and grooming task
  • Residue, cleaning history, damage and readiness for reuse

Out of scope

  • The biological condition and treatment of hair, scalp, skin or fur
  • Brushes whose working surface consists of a field of bristles
  • Clippers, razors and other tools whose primary action is cutting
  • Formulations and effects of shampoos, conditioners or styling products
  • Grooming procedures and service management beyond this comb's participation
  • Unrelated toothed components called combs in machinery or other domains

Why it exists Filled

Enable an AI agent to recognise a comb, assess whether its teeth and body are suitable for a particular task, and decide how it may be used, cleaned, stored or retired.

Distinguishing features Filled

  • Check for individually identifiable teeth projecting from a supporting body, with gaps through which strands can pass; this distinguishes a comb from a continuous smoothing blade.
  • Check whether the working elements form a defined tooth row or rows rather than a brush-like field of bristles; hybrid tools require component-level identification.
  • Check whether the intended action is strand separation, arrangement or retention rather than severing; toothed cutting tools need a neighbouring model.
  • Check whether a toothed hair accessory actually engages strands through its gaps; a pin or clip without this structure is not established as a comb.
  • Check intended use as well as silhouette before classifying a rake, fork or machine component with similar projecting teeth.

What robots and AI may and may not do Filled

Must not

  • Advise sharing combs during head lice or fungal infections.
  • Recommend grooming that causes pain or injury to animals.
  • Make demeaning comments about hair texture.
  • Misrepresent cultural combs as mere fashion items.

Only with a human decision

  • Grooming a distressed or aggressive animal.

May

  • Recommend a comb type for a hair or coat type.
  • Advise on cleaning and sharing combs hygienically.

Moral aspects Filled

  • Hair is tied to identity and has been a ground for discrimination.
  • Some combs carry cultural meaning for the communities that make them.

Who is affected

  • Users
  • Pets
  • Cultural communities

Owners Filled

Steward

The person who owns it.

Open questions

  • Does vr.tr.comb include retaining hair combs, animal grooming combs, specialised removal combs and powered or heated variants, or do existing registry entries own some of these?
  • Which existing Vercy world models already cover combs or their specialised forms and should supply the single publication of record?
  • Which measurements and practical observations reliably establish compatibility between tooth geometry, target strands and task without unsupported universal thresholds?
  • What manufacturer evidence supports material-specific cleaning, heat exposure and reuse limits for the comb variants included?
  • Which inspection criteria justify retirement, particularly for subtle tooth roughness, cracks or deformation that may be difficult to observe?
