The PriorityChef 2-stage and the Longzon 4-stage sharpener have a lot in common, but when it comes to effectiveness, the former has an edge.

Both sharpeners are well-designed with no deal-breaking faults. The PriorityChef has a lower center of gravity, while the Longzon boasts a more substantial body and a separate slot for scissors.

Neither device shaved a noticeable amount of material from the knife edge. You will get a decent edge with either, though the Longzon’s will be finer and smoother. 

Despite having only two sharpening slots, the PriorityChef could sharpen faster and to a higher level of keenness. These are deciding factors when it comes to convenient sharpeners, so the PriorityChef is the obvious choice for us.
