The Multi-Sharp 4 in 1 Garden Tool Sharpener can make all the difference. Using it is an easy way to keep a clean, sharp edge on knives, loppers, the Nijiri Gama Hoe and other straight edged tools. Hold the safety grip at the top and slide the sharpener over your tool or knife. It will sharpen scythes, grass hooks, weed knives, pruning knives, straight-edge loppers, kitchen knives and pocket knives. I use it on my kitchen knives because I haven't mastered the steel.
