Product Description
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.
The Smart Sharp 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.
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 KnivesWide 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.
