Buying Guide For The Best Electric Knife Sharpeners

Electric sharpeners are, without a doubt, one of the most essential tools we must have in our kitchen. However, before you decide which knife sharpener is suitable for you, go through our exclusive buying guide.

We have pinpointed the most important features you have to cross-check before you spend your hard-earned money on a product.

1. Performance and Flexible sharpening angle guide

Not every model will guarantee you a quality performance motor. We suggest you look out for the ones with the highest performance ratings so that the precision of your blade is not compromised.

And, as we said, different knives need different treatments. Always go for the sharpeners with adjustable angle guides. The standard ones that allow 15-degree to 20-degree adjustments are also good enough for most knives, for that matter.

2. Abrasive quality

Usually, the abrasiveness can be determined by the number of grits. Always opt for the ones with higher amounts of grit, to ensure the most excellent sharpened edge you can have. Do not buy if the material is not built with polished ceramic, carbide, or tungsten, because these are the best materials that build quality abrasives.

3. Safety and warranty

Safety is an essential feature you must look into, considering the risks involved with knife sharpening. We recommend you buy the models with non-slip base features and adjustable guides. These will reduce the chances of sudden movements. Also, make sure that the product has a minimum of a 1-year warranty period to ensure reliability.
