This machine is designed and manufactured in the World renowned Cutlery Laboratories of CATRA in Sheffield, England and is backed by over 50 years of product development and sharpness testing.

Its principle of operation utilizes the Spiral Interlock Grinding Wheel system, used extensively throughout the world for knife manufacture and resharpening.( beware of companies who claim this is a patented system, CATRA has been using the technique for over 35 years) By coupling this system with the high tech abrasive Cubic Boron Nitride (CBN) it provides CATRA Knife sharpeners with many advantages.

By selection of a particular sharpening angle, typically 30°, the user will consistently produce high levels of sharpness, as the edge angle is controlled by the grinding wheel diameter. This diameter does not change during the life of the surface of CBN abrasive. This fixed sharpening geometry means that all operators of the machine will achieve the same high levels of sharpness, irrespective of skill.

Each pair of interlocking wheels is capable of resharpening a blade at least 20,000 times and much more if a knife blade edge thinning system is operated. After which time the wheels can be returned to CATRA for recoating with abrasive, thereby keeping consumable costs low.

Different grades of abrasive are available which allow knives to be sharpened for different applications.

Very smooth	Fish and meat filleting
Smooth	General fish and meat processing
Medium	Vegetable and general kitchen use
Coarse	High speed sharpening and nonfood industrial use

Extensive sharpness testing on the ISO 8442.5 tester reveal that levels of sharpness produced on the CATRA model i100 are the highest consistently produced by any system. The edge life for given knife blade steel are also amongst the best achieved for re-sharpenable commercial use knives.

For the majority of uses we recommend a sharpened angle of 30°, which gives a good sharpness coupled with excellent life, however decreasing to 20° improves the sharpness, but increases the risk of damage to the edge and therefore premature loss of sharpness. The diameter of the grinding wheel controls the angle, so one machine may have different sets of wheels to give other angles. The change-over time for a pair of wheels is 5 minutes.

The machine is suitable for sharpening virtually all types of hand held knife including:

Boners Vegetable Steak/ scimitar DIY/ Craft

Filleters Slicers Folding/Pocket/Hunting Kitchen/ table

Cooks/Chefs Carvers Sporting/Collectors Fruit/ flower

even blades with concave curved edges can be sharpened.

Although the CBN abrasive is very fast and efficient, the knives do not become overheated during sharpening and so the use of a coolant is not required. This makes the machine pleasant to use and eliminates the use of a water bath, which quickly becomes a bacteriological hazard.

The machine has stainless steel covers and has water resistant electric motor and switches, making it suitable for use in food processing environments.

Available with fast or slow running motor. The faster motor allows the professional sharpener to operate under optimum conditions and the slow motor ensures the casual user does not become overzealous giving more control to the process.

This small machine is easily transportable and is ideal for in-house or mobile applications. When fitted into a service van the equipment runs from either a petrol generator or a 12v inverter connected to the vehicle battery. It has proved to be the ideal machine for mobile sharpening services, which many happy customers will testify to.

The machine is supplied with a full instruction manual and training film on CD, allowing users to self train in less than 20 minutes.
