Why Choose the SMART SHARP Knife Sharpener

Kitchen knives in a typical home kitchen don't get an easy life. Tossed into dishwashers, and slung away into kitchen drawers, knives can pick up minor dings and areas of micro corrosion.

Other pull-through sharpeners, although fast and easy to use, can 'catch' on these small notches on the blade which may cause further damage.

At the other end of the sharpening spectrum, methods such as whetstones and sharpening rods are gentler and can deal with minor blade damage. However, they also require a much higher level of skill and patience than the typical busy home chef has time for. Sharpening a single blunt knife properly with a whetstone can take 30 minutes or more.

The Smart Sharp has been designed to combine the best features of each of these sharpening methods into one single device.

It has the speed and ease of use of the traditional, single-stage pull-through sharpener. It also blends aspects from whetstone sharpening to protect your knives and makes sharpening gentler and more effective.

The Smart Sharp's first stage works on day-to-day nicks and imperfections on the blade edge, which allows for smooth and even sharpening on stage 2. The final stage removes any burs and polishes the blade for a brilliant finish.

The 3 stage process of the Smart Sharp gives you the best of both worlds to make it the most effective all-round knife sharpener on the market today.

How It Works

Stage 1 - Coarse Diamond Coated Rods

This stage 'roughens' the knife edge to prepare the surface for sharpening. It also smooths any nicks and imperfections that could cause the blade to 'catch' during the sharpening stage

Stage 2 - Hardened Tungsten Carbide

Now simply pull the blade through slot 2's precision angled tungsten carbide plates to create the perfect sharpened 'V' edge on even the bluntest knife.

Stage 3 - Fine Ceramic Stone Rods

For final edge honing. It removes any burs and gently polishes the blade edges for a super sharp finish.

 I've got to admit I'm impressed. The build quality is sturdy and solid, doesn't slip when in use and the results on the blades are sharp as using a steel. We're not talking standard knives here, we're talking paring knives, filleting knives, French cooks knife, to name a few. They've all been through it and come out of the 3 stage sharpener with neat edges that can shave the hairs off your arm with ease.

This will put a very good sharpening to any knife. Tried it on the bluntest knife I could find (Wouldn't cut a banana) brought it very much back to life. And would slice any soft tomatoes. Average household you need this sharpener.. Its brilliant... Will bring a scaryish sharpness. But you will feel the serrations on the blade. Buy one!

Smart Sharp Knife Sharpener showed me that yes, you can take destiny in your own hands and achieve sharpness with the swing of a hand. That’s in fact all it takes to sharpen the knives, one hand holding firmly the Sharpener, and one hand passing decisively the blade in the middle slot. I promise you, you will never doubt the wonder of the modern technic after trying one of these devices, it makes life and slicing vegetables so much easier.

I've used a butcher's steel for years but lacked the skill to get a really good edge, plus I've had too many accidents with it.  In the end I bought the Smart Sharp instead. And it's brilliant – it put a wonderful edge on my gran's ninety-year-old carving knives!

What type of knives is the Smart Sharp suitable for?

The Smart Sharp works on a huge range of kitchen knives - but NOT all knives! Please read below carefully to ensure that the Smart Sharp is suitable for your requirements:

Most kitchen knives in Europe & the USA are sharpened to an angle of approx 20 degrees. (Knives sharpened to this angle, we call Western style knives.) The Smart Sharp is a fixed angle knife sharpener which sharpens to 20 degrees and therefore designed for use with Western style knives of the following styles:

  • Straight Edge Steel Kitchen Knives (any length/shape)
  • Hardened Steel Knives
  • Wide serrated knives (bread knives)

What knives should I NOT use the Smart Sharp with?

Please ensure that you DO NOT USE the Smart Sharp for the following types of knives:

  • Ceramic knives, scissors or micro serrated knives.
  • Japanese Style Knives - We do not recommend that the Smart Sharp is used on specialist Japanese knives, including the knife brand 'Global' - this is due to the much narrower blade angles of these knives.
  • Whetstone/Steel Sharpened Knives – Not suitable for knives previously sharpened by long term use of whetstones or steels. Knives sharpened by these methods may have developed a different or uneven blade angle over time.
  • Visibly damaged knives – please inspect your knives before purchase to ensure that there are no visible notches or dents on the blade edges. The Smart Sharp will handle minor nicks and small areas of micro corrosion caused by day to day use, but it is NOT suitable for correcting more serious blade damage.

There is not a kitchen in the world that does not need this amazing sharpener!

I have old, abused, cheap knives that have never been sharpened in the 4 years since I bought them. They were so dull, I thought there would be no sense in trying to sharpen them, and was nearly about to toss them in the rubbish. Whilst looking through kitchen items on Amazon, looking for something else, I came upon the Lantana Smart Sharp sharpener... I'm so glad I took the chance on the product because I could hardly be happier with the results I've achieved! It is extremely fast & easy to use, and, though I had no need, the customer service is outstanding. They offered help should I need it, and gave clear & easy methods of contacting them directly.

This is one of the best kitchen tools in our cupboard. 

I decided to give this one a try, Within 10 minutes I had 7 really sharp knives. I tested them all on a tomato and a piece of paper. As the guy in the advert says, "Easy peasy, lemon squeezy". What a fantastic result! £10.99 very well spent. Instructions are to the point and easy to understand. Great that you don't have to read through pages of guff. 3 pictures with a how to - done!
This sharpener really is a great tool, bearing in mind that all my quality knives were useless until this arrived.
