Good sharpener

Fast shipping, it arrived in under a week. It looks like in the picture. It also has a soft rubber to support it on the table, which is neat.

Nice product

Nice sharpener to easily sharpen my knives without applying too much force.

Easy to use knife sharpener

This sharpener is very easy to use and does a great job at sharpening knives without the need to use a honing rode or wet stone which can be challenging (at least for me it is). I like the fact that it has many grind settings for various blades. Highly recommend!

Works well!
