Razor Cut 150×25×1

Hybrid-Bond CBN Sharpening Stones

Product Description

Kyoto Diamond Tools Ukraine (KDTU) proudly offers professional-grade diamond and CBN sharpening stones on a hybrid bond, specifically designed for precision sharpening and polishing. Available in 150×25×1 mm format on a durable 160×25×4 mm aluminum blank, these stones are a game-changing upgrade over standard electroplated stones.

🔹 Why Choose Hybrid Over Electroplated Stones?

✅ Smoother, More Controlled Sharpening

Our hybrid bond technology provides an exceptionally smooth sharpening experience with consistent feedback and superior edge quality. Formulated using advanced resins, non-ferrous metal powders, and self-renewing components, the stone resists clogging and retains cutting performance from start to finish.

✅ Performance That Lasts

Unlike electroplated stones, which lose cutting aggressiveness after ~20% of use, hybrid stones maintain their cutting power throughout the entire life cycle. You can refresh the surface using abrasive powders to restore maximum efficiency when needed.

✅ Up to 20x Longer Service Life

Electroplated stones feature a single abrasive layer. In contrast, hybrid stones contain multiple abrasive layers, meaning they last significantly longer:

• 315-micron grit → ~3 abrasive layers per 1 mm
• 50-micron grit → ~20 layers
• 2-micron polishing stones → up to 500 ultra-fine layers

This translates into unmatched longevity and cost-efficiency.

✅ Lower Long-Term Cost

Over the lifetime of one 1 mm hybrid stone, you’d typically need to replace 8 to 20 electroplated stones of similar grit. That makes hybrid stones not just better — but smarter from a cost perspective.

🔧 Compatible With All Popular Sharpening Systems

Perfectly suited for both freehand sharpening and guided sharpening systems, including:

• Hapstone
• TS-Prof
• KME
• Helicopter
• Apex-style systems, and more

📐 Tech Corner: Explanation of the number of layers in 1mm of sharpening stone

Want to know how many abrasive layers are packed into a hybrid stone? Here’s the math:

• Abrasive size is measured in microns (µm), where 1 µm = 0.001 mm.
• A 315 µm diamond grain = 0.315 mm → 1 mm / 0.315 mm ≈ 3.17 layers
• A 50 µm grain = 0.05 mm → 1 mm / 0.05 mm = 20 layers
• A 20 µm grain = 0.02 mm → 1 mm / 0.02 mm = 50 layers

👉 The finer the grit, the more layers — the longer it lasts.
