The Diamond Pro 2-Stage Knife and Scissor Sharpener uses diamond rods in the coarse slot to restore dull edges and ceramic stones in the fine slot to refine and maintain sharpness. Preset sharpening angles of 35 degrees combined for diamond and 37 degrees combined for ceramic ensure consistent results. Triangular ceramic stones also accommodate serrated blades, while floating ceramic rods sharpen both right- and left-handed scissors. A non-slip base and soft-touch handles provide control and stability during use. This versatile design supports routine maintenance and edge restoration in one compact tool.
