Overview
"Tools and Production" looks at the tools, machines and methods people use to make goods and provide services. These notes use Kenyan examples (farm level, Jua Kali artisans, small factories, and agro-processing) and are written for learners aged age_replace.
Key terms
- Tool: an item (hand or powered) used to do work (e.g., spade, hammer, sewing machine).
- Machine: powered equipment that does work faster or with more force (e.g., maize mill, tractor).
- Production: the process of turning inputs (labour, materials, tools) into goods or services.
- Process: the ordered steps followed during production (plan β make β test β pack β sell).
- Maintenance: care and repair to keep tools and machines working safely.
Types of tools and examples (Kenya)
Hand tools
Examples: spade, hoe, hammer, hand saw, knife, pestle & mortar.
Use: small farms, carpentry, food preparation (local shops).

Common production methods
- Job production: one-off products (custom furniture β Jua Kali carpenters).
- Batch production: small batches (bakery, soap making, tailoring).
- Mass/continuous production: large volumes (tea processing, flower packing).
- Artisanal production: craft and small-scale manual production (beads, baskets).
Kenyan mini case-studies
Smallholder maize mill:
Owner uses a diesel-powered mill (machine) plus sacks and scales. Tools: shovel, sieves, sack needle. Key points: regular maintenance of mill, fair weighing, good drying to prevent aflatoxin.

Jua Kali metal workshop:
Tools: angle grinder, welding machine, hammers. Production: chairs, gates, repairs. Key points: PPE (gloves, goggles), electricity safety, tool sharpening, and customer orders (job production).

Flower farm (export):
Uses mechanised packing lines and cold chain. Production must meet international quality standards; labour, tools and machines must be maintained to ensure consistent quality.

Safety & Maintenance
- Always use personal protective equipment: gloves, masks, goggles, boots.
- Switch off machines and isolate power before cleaning or repair.
- Regular checks: oil moving parts, tighten bolts, replace worn blades.
- Keep a simple logbook: date, problem, action taken, who fixed it.
Environmental & social considerations
- Reduce waste: reuse packaging, compost organic wastes, recycle metals and plastics.
- Energy choices: compare diesel, grid electricity and solar for cost & emissions.
- Fair labour: pay fair wages, ensure safe working hours and conditions.
Simple cost example (small maize mill)
Example calculation (per 100 kg maize):
- Cost of maize: Ksh 3,500
- Mill operator & fuel (diesel): Ksh 300
- Sacks & packaging: Ksh 100
- Maintenance allowance: Ksh 100
Quality control
- Inspect raw materials on arrival (no rotten produce, correct measurements).
- Sampling and testing: taste, weight, moisture content for grains.
- Keep records of batchesβhelps trace problems back to source.
Short classroom tasks
- List 6 tools used in your family or community and classify them as hand, power or machine.
- Draw a simple production flow for a product sold in your local market (e.g., mandazi, soap, baskets).
- Calculate a simple cost & selling price for a small product you can make at home.
Glossary
- PPE: Personal Protective Equipment.
- Batch: A set quantity made at once.
- Throughput: Amount produced per time unit.
Review questions
- Give two examples of tools used in Kenyan farms and state whether they are hand or powered.
- Explain why maintenance is important for machines in production.
- Describe one way small producers can reduce waste and save costs.
