# Sovereignty Module: Forge Your Tools

## Complete Blacksmithing Tool Making: From Bar Stock to Working Edge

Making your own tools is the ultimate self-sufficiency skill. This campaign covers forging essential hand tools, heat treatment, handle fitting, and tool steel selection.

| Hatchet | 1075 or 5160 | Flat bar 1.5x0.5 inch, 8 inches | Moderate | 2-4 hours | Drawing, punching, welding, heat treat |
| Drawknife | 1075 or old file | Flat bar 1.5x0.25 inch, 14 inches | Moderate | 2-3 hours | Drawing, bending, heat treat |
| Wood chisel | W1 or old file | 3/4 inch square, 8 inches | Moderate | 1-2 hours | Drawing, heat treat, handle |
| Screwdriver | Mild steel | 3/8 inch round, 10 inches | Low | 20-30 min | Drawing, flattening |

### Chapter 3: Heat Treatment

| Process | Temperature | Cooling | Purpose | Result |
|---|---|---|---|---|
| Normalizing | Cherry red (1,500°F) | Air cool | Relieve stress, refine grain | Soft, uniform structure |
| Annealing | Cherry red (1,500°F) | Very slow cool (in ash) | Maximum softness | Easy to file and machine |
| Hardening | Cherry to orange (1,475°F) | Quench in oil or water | Maximum hardness | Hard but brittle |
| Tempering | 375-600°F (by color) | Air cool | Reduce brittleness | Tough and hard |

Tempering colors (oxide colors on polished steel): 1) 375°F: light straw (files, razors, engraving tools). 2) 425°F: dark straw (drills, taps, punches). 3) 475°F: brown/bronze (axes, wood chisels, plane blades). 4) 500°F: purple (cold chisels, springs, knives). 5) 540°F: dark blue (screwdrivers, springs). 6) 575°F: light blue (soft springs). 7) Method: harden first (quench from cherry red). 8) Polish a section bright (remove scale to see colors). 9) Heat slowly (torch or oven) and watch for color. 10) When desired color appears, quench immediately. 11) Result: tool is hard enough to hold an edge but tough enough not to shatter.

### Chapter 4: Handle Making

| Handle Material | Strength | Shock Absorption | Durability | Availability |
|---|---|---|---|---|
| Hickory | Excellent | Excellent | Very good | Eastern N. America |
| Ash | Very good | Very good | Good | Widespread |
| Oak | Good | Moderate | Very good | Widespread |
| Maple | Good | Moderate | Good | Widespread |
| Birch | Moderate | Good | Moderate | Northern regions |

Handle fitting: 1) Shape handle to fit tool eye or tang. 2) For eye tools (hammers, axes): handle tapers to fit through eye. 3) Drive handle through eye from bottom. 4) Handle protrudes slightly above eye. 5) Drive steel or wooden wedge into top of handle (expands handle in eye). 6) Cross-wedge for extra security (two wedges at 90 degrees). 7) For tang tools (chisels, files): drill hole in handle for tang. 8) Heat tang and burn it into handle (creates perfect fit). 9) Epoxy or pin tang in handle for permanent attachment. 10) Ferrule: metal ring at top of handle prevents splitting.

### Chapter 5: Sharpening and Maintenance

| Sharpening Method | Grit Equivalent | Use | Speed | Result |
|---|---|---|---|---|
| File (mill bastard) | 40-60 grit | Heavy shaping, repair | Fast | Rough edge |
| Coarse stone (India) | 100-200 grit | Initial sharpening | Moderate | Working edge |
| Medium stone (Arkansas) | 400-600 grit | Refining edge | Moderate | Good edge |
| Fine stone (hard Arkansas) | 800-1,200 grit | Final sharpening | Slow | Very sharp |
| Strop (leather + compound) | 3,000-10,000 grit | Polishing edge | Very slow | Razor sharp |

### Reference Card

1. Old files make excellent tools (files are high-carbon steel already hardened; anneal them first, forge to shape, then re-harden and temper). 2. Leaf springs are versatile (automotive leaf springs are 5160 steel; tough and hard enough for knives, axes, and heavy-duty tools). 3. Normalize before hardening (normalizing refines the grain structure; always normalize at least once before the final hardening quench). 4. Temper immediately after hardening (hardened steel is brittle and can crack spontaneously; temper within minutes of quenching). 5. Tempering color tells hardness (straw for cutting tools, purple for impact tools, blue for springs; learn the oxide color scale). 6. Hickory is the best handle wood (nothing absorbs shock like hickory; it is the standard for hammers, axes, and striking tools). 7. A sharp tool is a safe tool (dull tools require more force, slip more often, and cause more injuries than sharp tools). 8. Make your tongs first (without tongs, you cannot safely hold hot metal; tongs are the first tool every blacksmith should forge).
