How to Use

• Electric Model Guide：
  

1. Place your metal blank completely flat on a solid, hardened steel bench block or anvil. (Do not stamp on wooden tables or soft surfaces).
2. Position the carbon steel stamp straight and completely flat against the metal surface.
3. Strike the top of the stamp firmly and squarely with a heavy metal stamping hammer.
4. One heavy, solid strike is always better than multiple light taps to prevent double or shadowed impressions.

Important Safety Notes！！！

• These carbon steel stamps are designed for cold pressing only. Heating them with a flame or electric tool will destroy the metal's temper and permanently damage the stamp.
• Always wear safety glasses when striking metal tools with a hammer to protect your eyes from potential metal splinters.
  * Coated with a light layer of oil upon arrival to prevent rust. Wipe the oil off with a dry paper towel before use. Do not wash with water. Keep dry and lightly oiled during storage.
