I have a sharp maker along with a 1/2 dozen other types of sharpeners. Its a quality Knife sharpener I would suggest springing for the diamond stones if you want to speed up sharpening very dull knives, for less $ you can get the deluxe Lansky system from Academy for like 39.00. I really like it I have two one for the camper one for the home. You can set it up and use the guides if you have a hard time with angles or you can simply hold the stones and sharpen free hand, It comes with a very coarse to a very fine stone. But really, and trust me I have experimented with a lot of sharpeners they all work just some takes more practice than others.
