Minosharp 550 - User Manual

Direction for use
1.
Pour water into the compartment of the sharpener and keep it there during
sharpening operation. The water in the wheel compartment serves always to rinse the
revolving ceramic whetstones and to prevent over-heating the knife blade. The
sharpener should always be rinsed with clean water by removing the cover after use.
2.
To keep the sharpener steady, firmly grip the handle with one hand.
3.
Next, place the knife blade vertically into groove No.1 COARSE with Blue, and move
the blade back and forth with SLIGHT PRESSURE 7 or 8 times, or as necessary.
NO HEAVY PRESSURE IS REQUIRED.
4.
Next, place the knife blade vertically into groove No.2 MEDIUM with Brown wheel,
and move the blade back and forth with SLIGHT PRESSURE 7 or 8 times, or as
necessary.
5.
Next, place the knife blade vertically into No.3 FINE with Yellow wheel, and move the
blade back and forth with SLIGHT PRESSURE 7 or 8 times.
It is very important not to apply too much pressure when passing the knife through the
sharpener, as doing so may cause damage to the wheels.
If undue pressure is applied, the wheels may break or become damaged. Such damage
will not be covered under our warranty, but replacement wheels are generally
available to purchase.
6.
When sharpening is complete please hand wash knife in hot water and carefully dry
with a dry towel or cloth before use.

This document describes the MinoSharp PLUS 3 knife sharpener, a device designed to restore the razor sharpness of knives using a three-stage sharpening process.

Function Description:

The MinoSharp PLUS 3 sharpener utilizes three ceramic wheels, each with a specific grit for different stages of sharpening:

• No.1 COARSE (Blue wheel): This is the initial stage for coarse sharpening.
• No.2 MEDIUM (Brown wheel): This stage provides medium sharpening.
• No.3 FINE (Yellow wheel): This final stage is for fine sharpening, completing the sharpening process.

The design incorporates an oblique angle for the ceramic wheels relative to the sharpening groove, which is crucial for restoring the knife's razor sharpness. The sharpener is designed to be used with water, which serves two primary purposes: to rinse the revolving ceramic whetstones and to prevent the knife blade from overheating during the sharpening process.

Important Technical Specifications:

The sharpener features three distinct ceramic wheels, color-coded for easy identification of their respective grits:

• Blue ceramic wheel: COARSE
• Brown ceramic wheel: MEDIUM
• Yellow ceramic wheel: FINE

The device has been tested and approved by CATRA (Cutlery and Allied Trades Research Association), an authority on knife sharpening techniques based in Sheffield, England, ensuring its effectiveness and reliability.

Usage Features:

The sharpening process is straightforward and involves several key steps:

1. Water Compartment: Before sharpening, water must be poured into the sharpener's compartment and kept there throughout the operation. This is essential for rinsing the whetstones and preventing blade overheating. After use, the sharpener should be rinsed with clean water by removing its cover.
2. Grip: To ensure stability during sharpening, the handle should be firmly gripped with one hand.
3. Sharpening Sequence: The knife blade is sharpened sequentially through the three grooves:
   • Stage 1 (COARSE): Place the knife blade vertically into groove No.1 (COARSE, Blue wheel). Move the blade back and forth 7 or 8 times with SLIGHT PRESSURE. Heavy pressure is not required and should be avoided.
   • Stage 2 (MEDIUM): Next, place the knife blade vertically into groove No.2 (MEDIUM, Brown wheel). Move the blade back and forth 7 or 8 times with SLIGHT PRESSURE.
   • Stage 3 (FINE): Finally, place the knife blade vertically into groove No.3 (FINE, Yellow wheel). Move the blade back and forth 7 or 8 times with SLIGHT PRESSURE.
4. Pressure Application: It is critically important to apply only light pressure when passing the knife through the sharpener. Excessive pressure can damage the ceramic wheels.
5. Number of Strokes: The recommended number of strokes varies depending on the knife brand and condition:
   • For GLOBAL knives: 7 or 8 strokes on each wheel.
   • For other brands: Start with 15 strokes on each wheel. If the knife is still not sharp enough, repeat the process with an additional 20 strokes on each wheel.
6. Post-Sharpening Care: Once sharpening is complete, the knife should be hand washed in hot water and carefully dried with a clean towel or cloth before use.

Maintenance Features:

• Rinsing: After each use, the sharpener should be rinsed with clean water by removing the cover to ensure cleanliness and longevity of the ceramic wheels.
• Damage Prevention: Applying undue or excessive pressure during sharpening can lead to breakage or damage of the ceramic wheels. Such damage is not covered under warranty. However, replacement wheels are generally available for purchase, indicating a design that allows for component replacement if necessary.
• Water Usage: Maintaining water in the compartment during sharpening is a key maintenance aspect, as it prevents overheating and keeps the whetstones clean.
