- Apply boiled linseed oil sparingly to prevent drying
- Avoid modern varnishes or polyurethanes

General preservation tips:
- Store in stable humidity and temperature
- Keep away from direct sunlight
- Support both head and handle to prevent stress
- Handle with clean, dry hands or cotton gloves

Remember that the goal is conservation, not restoration. Patina and signs of use are valuable aspects of antique tools and should be preserved rather than removed.

Framing hammers differ from regular claw hammers in several key ways:

1. Handle length - Framing hammers have longer handles (16-18 inches) compared to regular claw hammers (12-14 inches)
2. Head weight - Framing hammers are heavier (20-32 oz) than regular claw hammers (16-20 oz)
3. Face design - Framing hammers often have milled or waffle-pattern faces to prevent slipping when driving nails
4. Claw shape - Framing hammers typically have straighter claws optimized for nail removal in construction

In antique examples, these distinctions may be less standardized than in modern tools, but the general principles of heavier weight and longer handle for framing work remain consistent historical characteristics.
