Ultimate Blade / Knife / Chisel Sharpener

Ultimate Blade Sharpener A flexible and cost-effective sharpening block designed to accommodate 50mm strips of wet/dry paper or sandpaper for sharpening blades of various purposes and grades. Abrasive paper or cloth can be cut into 50mm-wide strips. The base features slots at both ends to securely feed the paper through, keeping it tight in position. The blade is held firmly by hand against the interchangeable angle block, which rides smoothly on a roller-bearing carriage for honing back and forth over the abrasive paper or cloth. When sharpening some knives, handles may obstruct access to the base of the blade, but using the angle blocks without the carriage can help reach these areas. The included files feature 15, 17, 20, 25, and 30-degree blocks, covering most sharpening angle requirements. A block blank is also provided for creating custom angles if needed. Some light sanding of the top surface of the base may be required to ensure it's completely flat and free from raised print defects. Required Hardware: 4x M4*16 button head bolts 4x M4 nuts 4x 608 bearings (8x22x7) (Sealed bearings to prevent filings entry) 4x rubber feet UPDATE: January 7, 2019 - The design now includes a 25 and 30-degree block with a 90-degree guide for chisels. CAUTION: Handling knives is extremely hazardous, and great care must be taken when using the sharpener. I disclaim all responsibility for personal injury resulting from the use of this sharpener; you assume full risk by using it!
