Sharpening Stones Set “Efim Pro” – Inspired by the Father of Flip-Sharpening Systems
About the Inventor Mr. Efim Dreer (Canada) is widely recognized as the inventor of the Flip-in-Sharp rotary mechanism, which revolutionized knife sharpening by allowing the blade to be flipped without removing it from the clamps. This principle has since spread globally and is now the foundation for leading sharpening systems such as TSPROF™, Hapstone™, Vector™, Jende Jigs™, Kazak™ and others. His second creation, the Efim-2™ rotating frame, became a breakthrough in sharpening training—allowing beginners to achieve a professional level of sharpness in just weeks, a result that traditionally would take years of practice to master. Recommended Set: “Efim Pro” As a master sharpener himself, Efim recommends the following combination of stones for maximum performance: Poltava Premium Lite CBN (Metal Bond) – 160/125μ (F 100) Poltava Premium Lite CBN (Metal Bond) – 100/80μ (F 225) Poltava Premium Lite CBN (Metal Bond) – 50/40μ (F 325) Boride T2 (F 600) Boride PC (F 1200) or Boride T2 (F 1200) This carefully selected lineup provides the perfect balance for coarse grinding, intermediate sharpening, and final polishing. Key Advantages Exceptional Longevity – Poltava Premium CBN stones last dozens of times longer than traditional waterstones. Cleaner Sharpening – Can be used without oils; however, water with soap or light fluids make the process smoother and more enjoyable. Universal Compatibility – Fits popular systems like Kazak USA, RUIXIN, TSPROF, Hapstone, and more. Durable Metal Bond – Delivers outstanding wear resistance and reliability for consistent results. Perfect for Beginners and Enthusiasts – The “Efim Pro” set is ideal for anyone looking to achieve professional-level sharpening at home. Usage and Preparation Before Sharpening: Inspect the stone for cleanliness or surface damage. Wipe off residue from previous sessions using a damp cloth. Choosing Grits: Coarse grit for restoring dull or damaged edges. Fine grit for polishing and finishing. CBN and diamond stones are especially effective on high-carbon and hard steels. Sharpening Technique: Ensure the knife is fixed securely, either in a system or manually. Maintain the recommended angle (typically 15–20°) during sharpening. Use steady, even strokes along the cutting edge. Avoid rocking or changing angles mid-stroke. Lubrication Tips: Expert Pro series performs best with water and soap. Premium series shows best results with light sharpening oils. Do not use machine oil, motor oil, or industrial lubricants. Cleaning & Maintenance: After use, wipe the stone clean with alcohol or sharpening oil to remove metal debris. If necessary, rinse with water and mild detergent, then dry thoroughly. Store in a clean, dry location. Refresh the stone’s surface using silicon carbide powder or specialized abrasive cleaners. Final Note By following these guidelines, the “Efim Pro” sharpening set will provide consistent, professional-level results while maximizing the lifespan of your diamond and CBN stones.
