I have a Sharp Maker that I use pretty often; always with the top clipped on and the brass guard rods. I just wonder though – how often do those brass rods do their job? I understand they are supposed to protect your hand, but what is the event that would result in cutting yourself? The only thing I can think of is the blade skipping over the top of the rod and coming down on your hand. But I never start sharpening at the top of the rod; always at least an inch down.
