Tool control

Tools become extensions of skill—but not automatically. The wrong simulator can make later performance worse.

Explanation is not permission.

This dossier explains the evidence and its limits. It is not a diagnosis, personal recommendation, assessment, clearance, performance promise or training programme. Actionable teaching appears only when the canonical Power record explicitly authorises it.

Complete bounded explanation

What this power means.

Capability to develop or express tool control in a declared context without inheriting broader claims.

What the current evidence supports

Control of a specific tool can be learned, retained and sometimes transferred, but poor interface fidelity can produce negative transfer.

How to observe or measure it without overclaiming

Path, contact force, damage, error, product quality and completion time must be declared together; speed alone is unsafe.

Myth

Master every tool by feel

Metric

Force, path, damage and accepted product on one named tool

Boundary

Control of one interface cannot certify another or grant a credential.

Negative and limiting findings

  • A haptic VR programme produced worse transfer performance than control on a porcine model.

Claims this evidence cannot support

  • Master any tool fast
  • Simulation certifies competence
  • Realistic haptics always help
  • Use powered tools to test yourself

How to learn this Power now.

In a qualified training fixture, the learner completes three marked passes with the approved hand tool inside the tolerance band, without loss of control or material damage.

  1. Get readyPrepare one instructor-approved craft or trade task using a low-risk hand tool on clamped sacrificial material
  2. Learn the method8 concrete steps teach the permitted method from start to finish.
  3. See right and wrong5 comparisons show correct or safer execution beside common wrong or riskier choices.
  4. PractiseAt later instructor-led sessions, retain same tool class & sacrificial material while changing only marked path. One session repeats original corridor; another introduces one approved bend or length change. Tool, material or operating position is not changed until three passes stay controlled & damage-free in two sessions.
  5. Check progressFor Tool control, measure Force, path, damage and accepted product on one named tool. Keep the tool control fixture stable. Target: In a qualified training fixture, the learner completes three marked passes with the approved hand tool inside the tolerance band, without loss of control or material damage. Log tool control errors, prompts, burden and stops.

Authority boundary: Titan teaches the complete method; a qualified person controls the parts that require supervision, clearance, specialist equipment, load, dose or progression. The method is Power-specific; its actionability follows this treatment.

Current teaching and evidence boundary

The next gate remains visible.

External confirmation is required before higher-authority use because: a clinical, high-risk or regulated configuration; cultural, community-rights or affected-person authority; a restricted safety or legitimacy boundary.

A Power-specific tutorial is available at /tutorials/pwr-154/. It contains a plain-English method, 8 ordered steps, a worked example, right-versus-wrong comparisons, specific mistakes and corrections, practice, measurement, accessibility, stopping rules and evidence. Its supervised mode remains controlling.
