It might be counterintuitive, but the sharper the knife is, the safer it is to use, since a sharper knife requires less force to slice. This Chef’s Choice sharpener uses 100% diamond wheels to manually sharpen both serrated and non-serrated knives. Today’s price of $22 is a good ~$15 discount from the usual and an all-time low.
