AnySharp – EDITIONS – Hands Free Knife Sharpener - Easy to Use Sharpening Tool with PowerGrip Suction Base and 20-Degree Pre-set Angle - For All Knives: Chef’s, Serrated, and Hardened Steel - Blue

Exactly what I was looking for. Very sturdy suction to hold it in place. Sharpened my kitchen knives with a few quick draws through.

What a good little device very safe to use and really sharpens knives well but you do have to replace it after a year or so

Works ok, but not as good as described.

It works as advertised. Sucction cup is reliable.

This sharpener is really easy to use. Clamp it onto the tabletop and just glide your dull bladed knife thru a few times and test the new sharpness of the blade. For such a simple device I was able to sharpen our pocketknives in less than a minute.

Edit - After less than a year, this stopped working for me, unfortunately. Started off great, but even with pretty moderate use in a house that doesn't do much knife-sharpening, it didn't hold up for me, unfortunately. Original post 8 months ago - I got this little number a few days ago and sharpened over a dozen knives in the house in less than an hour. I had been holding off on replacing an older electric knife sharpener because I didn't want to spend fifty to a hundred bucks, but this little number is cheap, quick and put a great edge on all my blades. PLUS, it's super compact, so I can just toss it in the kitchen drawer.

Great little sharpener for any size or type of knives. Sharpened all our knives in about 10 minutes. Love the suction to clamp on the countertop for ease of use.

Works as described
