Copper and steel are the two most common nail materials for sadhu boards. Copper nails are the traditional choice — softer to the foot, warmer in feel, and associated with the Ayurvedic view that copper carries subtle energetic properties. Steel nails are harder, sharper, more affordable, and hold their tip longer. In practice both are safe when spaced correctly and hand-fitted for even height. Copper costs more and can bend under aggressive practice; steel resists deformation. METADESK offers both materials from its Kostopil workshop; production lead Roman Karas hand-fits each nail regardless of material.
Key facts
- Copper: softer, warmer, traditional, more expensive.
- Steel: harder, sharper, cheaper, longer-lasting.
- Both safe on well-fitted boards.
- Copper can bend on heavier users or aggressive practice.
Frequently asked questions
Which feels sharper?
Steel feels marginally sharper because it resists compression better than copper.
Does copper offer real energy benefits?
This is a traditional Ayurvedic view; there is no clinical evidence, but many practitioners prefer the feel.
Which lasts longer?
Steel. It resists bending under heavier users or long-duration standing.
Can METADESK combine materials?
