SHARPENING SUGGESTIONS: Orbital Rotary Cutter Blade Sharpener
1. Be sure the blade is not revolving as you rotate the sharpening wheel around the periphery of the rotary cutter blade. To do this, clean the blade, blade support and clamping surfaces, of the sharpener, with alcohol to remove any oil that may be allowing the blade to slip and rotate.
2. Make sure the blade is clamped tightly enough to prevent rotation while sharpening. It doesn’t take a great deal of pressure to clamp the blade but it must be tight enough to prevent rotation of the blade.
3. Pressing downward too hard on the sharpening wheel knob, can roll the rotary cutter blade’s cutting edge, thus creating a dull blade. To prevent this, apply only a “light” downwards pressure on the cutting wheel knob while sharpening the rotary cutter blade.
4. Do not rotate the diamond cutting wheel down against the plastic rotary cutter blade support surface without a blade present. This will clog the diamond cutting wheel with plastic material, and it will not sharpen a rotary cutter blade unless the plastic material is removed as outlined below.
5. Start with the Coarse Diamond Sharpening Wheel the first time you re-sharpen a rotary cutter blade in order to remove the majority of the metal, and to match the cutting angles on both sides of the rotary blade to the face angle of the Diamond Sharpening Wheel.
6. Use the Fine Diamond Sharpening Wheel only to dress the rotary cutter blade in the final sharpening process to create the razor sharp edge.
7. If the Orbital Rotary Cutter Blade Sharpener seems to not sharpen a blade as quickly as the first time you used it, check the diamond sharpening wheel cutting surface to insure that it is not damaged, or clogged with foreign matter.
8. To clean the diamond sharpening surface of the sharpening wheel. Use any of the following cleaning methods. The idea is to remove all of the foreign material and to re-expose the diamond sharpening surface without damaging it.
a. Rub the diamond sharpening surface with fine scotch bright (often found on a pot scrubbing sponge), fine steel wool, or fine brass, or steel brush until it is clean.
b. Or, rub the diamond sharpening surface with a pencil eraser.
c. Or, clean the diamond sharpening surface with acetone.
9. Remember that the sharpener only sharpens one side of the Rotary Cutter Blade’s cutting edge at a time, so be careful to sharpen each side of the blade the same amount, or number of turns each time you sharpen it. Always use sharpening oil!
10. To insure that all very fine burrs have been removed from your re-sharpened rotary cutter blade. Place the re-sharpened blade back into the rotary cutter handle, and then lightly cut a few times down into a stack of old newspapers or magazines that have been placed on a protected surface. This will remove all the fine burrs and demonstrate the sharpness of the re-sharpened blade. Remember, paper is abrasive so a few passes is all that is needed.

Q. Why is a sharp needle or blade important?
Dull needles can snag fabric, enlarge entrance holes and cause thread breaks. A dull blade is downright dangerous, since you must use more force to make a cut, and if you slip you can cause serious injuries!
