What are the differences between a honing rod and a sharpening rod, and how do they each contribute to maintaining the sharpness of a knife?

A honing rod is used to straighten and realign the edge of a knife, while a sharpening rod is used to remove metal and create a new edge. Honing rods help maintain the knife's sharpness by keeping the edge aligned, while sharpening rods help restore sharpness by removing material to create a new edge. Both tools are important for knife maintenance, with honing rods used more frequently for regular upkeep and sharpening rods used less often for more intensive sharpening.
