The Diafold® Kit includes (2) Double Sided Sharpeners (FWFC, CFWE), Serrated Knife Sharpener (FSKF) and Flat File (FFC). Kit grits include Blue-Coarse diamond (45 micron/ 325 mesh) to quickly restore a neglected edge; Red-Fine diamond (25 micron / 600 mesh) for a razor sharp edge; Green-Extra-Fine diamond (9 micron / 1200) to polish and refine a razor edge after sharpening with a coarser diamond; White-Ceramic surface (7 micron / 2200 mesh) to provide the finest polished edge of all bonded abrasives. All Diafold® models are: sized 9 1/2" open / 5" closed and have folding plastic handles that protect the sharpening surfaces when not in use; hone/sharpen in a fraction of the time required by conventional files/sharpeners; no messy oils needed—use dry or with water; durable construction will provide years of consistent performance and reliable service; Made in USA.
