Roll-Sharp : Fiskars sharpener
Thanks to a functional design and to a research for safety, Fiskars produced a knife sharpener useful to maintain the edge of knives that lost the sharpening of the cutting side due to wear and tear.
Roll-Sharp blade sharpener must be placed on a flat surface and the knife must be placed in the guide.
Moving the knife forward and backward 4-5 times and pushing lightly the knife will recover the right sharpening.
Length 15,5 cm.
