2. Kitchen IQ Edge Grip 2 Stage Knife Sharpener

KitchenIQ 50009 Edge Grip 2 Stage Knife Sharpener

Specs at a glance

  • Ergonomic handle
  • Durable two sharpening slots; ceramic and carbide
  • Manual
  • Portable

This manual knife sharpener can have you fooled because of its size and you may second guess its worth on your kitchen counter. The second reason that may cause you to overlook it is the very low price it retails at.

Interestingly, the Kitchen IQ Edge Grip 2 Stage Knife Sharpener is worth considering for exactly the same two reasons mentioned above: size and price. What sets it apart in the race for knife sharpeners is both its build and cost.

This practical unit is designed and constructed by Smith’s Consumer products, Inc. a company renowned for creation of expert edges since 1886.The edge grip makes it so easy to use so the manual aspect should not be daunting for anyone in the kitchen. In fact it’s almost effortless because all that is required of you is to simply hold the ergonomic handle and swipe your knife through either of the two slots several times beginning from the hilt and pull.

The slots are angled at 20-22 degrees which is perfect for most knives as this seems to be the default factory angle.

The Edge Grip 2 has a two stage sharpening system, coarse and fine. For best results, use the coarse slot which is made for blunt and dull knives at first. A few pulls and you will be pleasantly surprised to see them sharp as a razor. Then pass them through the fine tile slot that will give them a softer and sharper finish.

Knives that are fairly sharp can be passed through the fine slot which is made of fine- grit ceramic just for a re-touch to make sure they stay in tip top shape and on the ready whenever you need them.

This unit features the ‘edge grip’ which is unique because it allows you to sharpen both small and longer knives. Longer knives have a tendency to drag on the counter top as you attempt to sharpen and can easily get damaged or worse, damage your precious granite or wooden counter top.

The ‘edge grip’ feature prevents this possibility as the design of this unit allows you to place it on the edge of a work top thus availing more room and flexibility to work with when sharpening.

You can comfortably use this manual sharpener on top of a work surface to sharpen most knives and the additional flexibility is a welcome thought when you need to sharpen large knives.

Its portability is simply remarkable as you can take it with you and use it anywhere from a yacht to a camping trip or a mountain hike. Storage in your kitchen is a breeze with the Edge Grip 2, as it can fit in with the knives in the same drawer.

Pros and cons of the Kitchen IQ Edge Grip 2 Stage Knife Sharpener

PROS:

  • Very portable
  • Durable
  • Easy to use
  • Affordable and therefore very easy to replace
  • Rubber base for stability
  • Ergonomic built for better handle and grip
  • Very effective two stage system, coarse slot made of carbide and a fine slot made of ceramic.

CONS:

  • Cannot sharpen serrated knives
  • Can easily get lost or misplaced due to its size

Verdict

Given the simplicity, stability and sturdy build of this unit not to mention how effective at sharpening it actually is, the price is definitely worth it.

The portability adds to the convenience as it can be used both indoors and outdoors and it does not require electricity.

In fact some would argue that this option is ideal for them and a preferred choice to stone, steel and electrical options owing to how hassle-free it is for such a price tag.  Definitely the best bang for your buck.

Diamond is one of the hardest substances on the face of the earth and ideal for sharpening. By pulling even the dullest of knives through this slot, the diamond wheel sees to it that an angle is formed on both sides a knife’s bevel edge.
