2 Knife Sharpener Recommendations from WickedLocal.com
Christopher Kimball at WickedLocal.com recommends 2 knife sharpeners:
We suggest the Chef's Choice Knife Sharpener (only buy the 3-slot, not the 2-slot model), but that will set you back well over $100. A cheaper alternative, but not good with a really dull knife, is the AccuSharp Knife and Tool Sharpener for a mere $11.71
The Chef's Choice 120 Diamond Hone Professional Knife Sharpener
can be found on Amazon.com for around $150. However, it does have 3 sharpening slots and uses spring loaded guides to hold the knife in place to ensure the proper angle. If you have the money and want sharp knives, this electric option sounds like a great choice.
The manual AccuSharp 001 Knife Sharpener
which is much less expensive, is small in size, light weight and garners a 4.5 customer rating with over 3,000 reviewer. On a tighter budget, this looks to be a solid choice.
