Product Description

Description of Diamond Sharpening Cards


The HUAYIDA Diamond Credit Card Sharpeners or diamond sharpening cards are designed to deliver professional sharpening performance in a compact, portable form. Measuring just 84 x 50 x 1.6mm, each stone is lightweight and easy to carry — perfect for woodworkers, outdoor enthusiasts, hobbyists, and professionals who need sharp tools wherever they work.

Each sharpener features a micronized monocrystalline diamond surface, providing fast, smooth, and consistent sharpening results. With two grits (300 and 600) on one double-sided plate, you can handle both rough sharpening and fine honing without needing multiple stones:

  • 300 grit (coarse) – Quickly restores dull or damaged edges.

  • 600 grit (fine) – Refines and polishes the edge to a razor-sharp finish.

For optimal results, use the sharpener with lapping fluid to prevent clogging, reduce friction, resist rust, and keep both the tool and stone clean during use.



Key Features


Dual-Grit Design (300 & 600 grit) – Combines coarse and fine sharpening in one convenient tool.

Compact & Portable – Credit card-sized (84 x 50 x 1.6mm) for easy storage in your pocket, wallet, or toolbox.

Fast, Consistent Sharpening – Monocrystalline diamond surface ensures even, efficient cutting with minimal effort.

Durable & Long-Lasting – Engineered by HUAYIDAtools for years of reliable, professional performance.

Protective Storage Wallet – Color-coded sleeve keeps your sharpener safe, clean, and easy to organize.

Use with Lapping Fluid – Improves sharpening action while preventing clogging and corrosion.

Versatile Application – Ideal for carbide and HSS tools, knives, chisels, woodworking blades, and more.

All-in-One Solution – Double-sided stone eliminates the need for multiple grit plates.

Convenient for Field Use – Keep one in your wallet, tool kit, or backpack for quick sharpening at job sites, in the garden, or out in the field.
