Basic Usage
* IMPORTANT:
Do not sharpen newly out-of-the package blades! The Rotary Blade Sharpener is
used to hone a dull blade to a near factory-sharp edge. You will not be able to achieve a factory-
machined edge. Damage and nicks on blades caused by pins, etc. are generally irreparable.
To use your sharpener, make sure that the Blade Guide is secured against the sharpening stone.
Insert the blade of your rotary cutter through the blade entrance at either end. When using your
sharpener make sure that your rotary cutter blade remains vertical at a 90° angle during the whole
process. Never angle your blade to cut in towards the sharpening stone as this may damage the
stone and dull your blade.
To sharpen your blade
• Hold your cutter at roughly a 45° angle to the sharpener.
Cutters with larger blades (60mm) may need
to decrease this angle to ensure that bottom of the blade aligns with the stone.
• Start at one end of sharpener track (not in the middle) and roll your cutter back and forth.
• Confirm that the blade is actually rotating as it travels through the slot.
•
Pass the blade back and forth around 20 times
(The number of times the blade will need to pass
back and forth will depend on the dullness of the blade. Fewer strokes may be required in the
sharpening process depending on the sharpness of the blade).
•
Rotate the sharpener 180° and repeat the sharpening process for the other side of your blade.
• Repeat this process on both sides, decreasing the number of passes by half.
• Repeat again decreasing by half.
• Test the sharpness of your blade by cutting a piece of fabric.
Depending on sharpness of the blade, the sharpening process may need to be repeated.
