Essential Hand Tools Reference

Why this matters

The wrong tool wastes time + risks safety + ruins materials. Every trade has its essentials, plus universal hand tools every tech carries. The shop that invests in quality hand tools spends 50% less on tool replacement + has techs who arrive prepared. This is the field card.
