The world of guided knife sharpeners is divided into clamp-based and working table-based. Either have strengths and weaknesses. Table-based sharpeners offer the even sharpening angle across whole blade. Clamp-based sharpeners offer the consistency in every point during whole sharpening process. Table-based are more universal, while clamp-based have shorter learning curve. Hapstone knife sharpener belongs to both worlds now with Rotating Clamp System upgrade.

Rotating Clamp System will be available from Feb 15th.

All natural whetstones are different. Virtually every country in the world has its unique natural stone. Belgium has Belgian Blue Whetstones known as BBW. BBW has a high garnet content, and garnet crystals give it extraordinary properties. Usually sharpening grains must have sharp edges to be high-abrasive. Garnets have dodecahedron shape (ball with 20 vertices) which perfectly suits purpose of ultra-fine sharpening and polishing.
