Poly Diamond Emulsion – 4 Micron Stropping Emulsion

 The Jende Poly Diamond Emulsion (4 micron) is designed for users who want a fast-cutting yet refined stropping compound. It sits in the mid-fine range, making it ideal for improving sharpness after sharpening stones while still maintaining good cutting performance. Whether you’re finishing a kitchen knife, woodworking tool, or straight razor, the 4 micron emulsion delivers a consistent, controlled polish.



High-Quality Poly Diamond Formula

Jende Poly Diamond Emulsions are among the highest quality stropping compounds available. Each formulation is custom-developed to provide fast cutting action and reliable results. The polycrystalline diamond particles break down during use, allowing them to reach microscopic grooves in the steel and produce a more even, refined finish compared to traditional abrasives.

The color-coded labels make it easy to identify grit sizes quickly, and they correspond directly with Nanocloth strops. This helps maintain an organized sharpening progression, especially when working with multiple grits.

Available Bottle Sizes

Jende Poly Diamond Emulsions are available in convenient squeeze bottles:

The 7ml bottle typically provides:

  • About 2–3 loadings for Nanocloth strops
  • About 7–10 loadings for leather strops

For larger strops, the 25ml or 50ml options are more practical and economical.

Compatible Strop Materials

The 4 micron poly diamond emulsion works exceptionally well on:

  • Nanocloth strops
  • Cow leather strops
  • Kangaroo leather strops

Each surface offers slightly different feedback, but all benefit from the fine and consistent abrasive action of poly diamonds.

Performance on Different Materials

Diamond abrasives are extremely versatile and cut through all steel types efficiently, including:

  • High-carbon steels
  • Stainless steels
  • Powder metallurgy steels
  • Ceramic blades

The poly diamond structure allows the particles to reach tiny surface imperfections, resulting in smoother edges and improved consistency. This makes the 4 micron grit particularly useful for refining edges after mid-range sharpening stones.

When to Use 4 Micron

The 4 micron emulsion is commonly used for:

  • Refining edges after 800–2000 grit stones
  • Improving slicing performance
  • Preparing for finer stropping stages
  • General-purpose finishing for kitchen knives

If you need more aggressive cutting action, Jende also offers Max Concentration Emulsions, which increase abrasive density for faster results.

Conclusion

The Jende Poly Diamond Emulsion in 4 micron provides an excellent balance between cutting power and finishing ability. With easy application, consistent performance, and compatibility across multiple strop materials, it’s a reliable choice for anyone looking to refine their edge while maintaining strong cutting performance.

Jende JIGS Sharpening System – How It Works and What to Expect

Image
Sharpening knives with consistent angles is difficult when done freehand. The Jende JIGS sharpening system is designed to control the sharpening angle and guide the sharpening motion. This helps users maintain repeatable results. What the Jende JIGS System Does The system holds the knife in place while the sharpening stone moves along a guided rod. This keeps the angle fixed during the sharpening process. Because the angle stays the same, metal is removed evenly across the edge. The video explains that this setup removes guesswork. Instead of adjusting hand position during sharpening, the guide controls the movement. This makes the process more predictable. Knife Clamping The knife is secured in a clamp. Once tightened, the blade remains in position. This allows the user to sharpen both sides without changing alignment. The clamp also helps when working on longer blades. Angle Adjustment The system includes an angle adjustment mechanism. The user sets the sharpening angle before start...

Jende 10×4 Glass Lapping Plate with Silicone Carbide Powders - Complete Guide

Image
The Jende Double-Sided Glass Lapping Plate measures a generous 10″ x 4″ and includes coarse, medium, and fine silicon carbide lapping powders for versatile stone maintenance. Crafted from ½″ thick float glass , it features two functional surfaces. One side is etched for use with lapping powders to efficiently flatten sharpening stones, while the opposite side is perfectly smooth and flat for precision work. The etched side has 0.5 mm deep grooves , making it more aggressive for lapping. These grooves also help channel swarf away, reducing stiction especially when working with finer grit stones. The smooth side accommodates a half-width sheet of full-size sandpaper or lapping film , and can also serve as a reference plate for flattening knives, chisels, and plane blades. Using the Lapping Side Lightly wet the glass surface (avoid pooling water). Evenly sprinkle the desired grit of lapping powder. Pre-soak your sharpening stone if required. Draw a pencil grid on the stone’s surfa...

1×6 Naniwa Chosera Water Stones | Fits Edge Pro, TSProf, Hapstone

Image
The 1×6 Naniwa Chosera Water Stones are designed for guided sharpening systems and offer consistent grit performance across a full sharpening progression. Known for precise manufacturing and uniform abrasive distribution, these stones provide controlled cutting and polishing while maintaining predictable feedback during sharpening. These stones are available in eight grits , organized into three categories: Coarse, Medium, and Fine , allowing users to build a complete sharpening progression from repair to polishing. Coarse Grits (400, 600, 800) The coarse range is used for stock removal, edge repair, and reprofiling . These grits remove deeper scratches created by diamond plates, abrasive belts, or heavily worn stones. They are typically not used as finishing stones. Instead, they prepare the edge for the next stage in the sharpening progression. Common uses: Edge repair Reprofiling bevel angles Removing chips Preparing for medium grit refinement Medium Grits (800, 1000, 2000, 3000) ...
