1. Colonial Needle 45 mm Rotary Blade Sharpener – Best in manual design

Colonial NeedleSharpener is a manual rotary blade sharpener that sharpens dull spots and burrs on a blade with ease. To use this tool, the blade is placed between the circular-shaped disks and tightened to have a firm grip. With a little effort on the handle and a clockwise turn, the twist causes abrasion against the disk which in turn sharpens the blade to smoothen the edges.

 For efficiency, this blade sharpener offers a two-way (dual) sharpening mode. By removing from the disk and turning the blade the other way, a second sharpening can be done to restore dull edges to sharper ones.

If used habitually, the disk’s durability extends up to half of the year before replacement is necessary. It is safe, time saver, and cost-effective.
