Frequently Asked Questions
Q: What materials can the 20mm leather corner punch cut through?
A: This 20mm carbon steel leather corner punch is designed primarily for leather materials including belts, wallet panels, bag straps, and notebook covers. It works best on vegetable-tanned or chrome-tanned leather of light to medium thickness. It may also be used on thinner craft materials such as felt or heavy fabric, though performance will vary by material density.
Q: Do I need a mallet or hammer to use this punch cutter?
A: This tool is designed for manual hand-operated use. For softer or thinner leathers, firm hand pressure may be sufficient. For thicker or denser leather, placing the tool on a hard cutting mat and applying a mallet or hammer strike to the top of the handle will produce the cleanest, most consistent half-round cuts.
Q: How do I maintain the sharpness of the carbon steel blade?
A: To keep the blade in top cutting condition, store the punch in a dry environment to prevent rust, and lightly oil the blade with a few drops of machine or mineral oil after use. Avoid cutting on glass or metal surfaces — always use a wooden block or leather cutting mat to protect the cutting edge and extend the tool's life.
