Cast Iron Strop: The Ultimate Finishing Touch for Razor Sharpness
The PDT Cast Iron Strop is a unique and highly effective tool for achieving a polished, razor-sharp edge on your knives and tools. Unlike traditional leather strops, the cast iron surface provides a perfectly flat and stable platform for honing, ensuring consistent and precise results.
Recommended grain sizes per strop:
- Strop Soft - for grain sizes from 28/20 to 14/10 µm (ca. JIS 650 - 1700)
- Strop medium - for grain sizes from 7/5 to 3/2 µm (ca. JIS 3000 - 4000)
- Strop hard - for grain sizes from 3/2 to 0.5/0 µm (ca. JIS 5000 -15000)

How it works:
The cast iron strop utilizes the principle of abrasive lapping. When used with a polishing compound, the microscopic abrasive particles embed themselves in the surface of the cast iron, creating a honing surface similar to that of a diamond or CBN stone.
This makes the cast iron strop incredibly versatile, allowing you to:
- Work with loose abrasives: Apply pastes, emulsions, or suspensions directly to the strop
- Charge the strop: Create a dedicated honing surface by working a fixed abrasive into the cast iron
- Combine methods: Apply a paste to a charged strop for enhanced performance, especially with coarser grits
