Over 370 of these knife sharpeners in use in supermarkets, over 420 in use in retail butcher shops, 55 in use restaurants, 200 in food manufacture/ processing and 25 in use in small sharpening services and shoe/heel bars
The sophisticated principle of Tapered Spiral Interlock grinding gives a convex section cutting edge of a constant angle( often known as Gothic Arch) without any burrs or edge protrusions. The edge generated is ideal for immediate use and can easily be maintained during the working day using a sharpening steel.
Small replaceable grinding wheels coated with the high-tech abrasive Cubic Boron Nitride give many advantages to CATRA knife sharpeners, including:
The machine only generates metal dust which is kept within the main wheel guards by the use of magnets, any metal particles escaping from the knife entry slot are captured on the surface of the machine again by the influence of the built in magnetic field. this virtually eliminates any metal dust leaving the are of the machine and contaminating work surfaces and foodstuffs. Note however the knife blade is not magnetised within this system.
The grinding wheels have a life normally in excess of 6000 sharpenings dependent on the size of knives sharpened and can then be replaced in less than 5 minutes. This makes the cost of resharpening less than 1.5p( 2c)/knife, but the gains in productivity through using a sharp knife can save you significant amounts of cash.
In stores, butcher shops etc typical sharpening wheel life is 2 to3 years
| Brand new never been sharpened | 50 seconds |
| Heavily worn blade never been sharpened by CATRASHARP before | 30-40 seconds |
| A worn blade after a good amount of work, but was last sharpened by CATRASHARP | 5-10 seconds |
This smallest machine of the commercial range of powered sharpeners produced by CATRA is ideal for businesses that have between 1 and 20 knife users or for low volume high quality knife makers.
Manufactured from stainless steel and aluminium it is suitable for use in food processing environments. This is a extremely well engineered and manufactured product, it is not a toy or a domestic sharpener, its is at the fore front of sharpening technology and will give you many years of service.
Safety overload system built in to the machine prevents overloading the motors and more importantly prevent excessive sharpening and rapid loss of blade width which can easily happen on other more aggressive knife sharpeners.
Note - with the alternative fixing of micro-fine diamond coated honing wheels the machine is ideal for sharpening CERAMIC knife blades to the original manufacturers standard or better.
Marinized version option is available for on board use in fishing vessels, trawlers and factory ships
