How to sharpen a standard blade on the BlitzBlade Sharpener

Step 1

Switch the machine on by pressing the Green Button.

Step 2

WARNING — Beware of the large rotating wheel on the side of the machine.

Step 3

Place the knife’s blade with the flat-side against the golden metal guide. The widest part of the blade, closest to the handle, should be the starting point.

Step 4

Holding the blade stable against the guide, slide it up until it makes contact with the moving belt. Immediately pull to the side while the blade’s still in contact with the moving belt. Maintain steady contact to ensure smooth, even sharpening.

Step 5

Follow the curve of the blade while sharpening. Repeat the action.

Step 6

Flip the knife over to sharpen the other side of the blade, and repeat the same action (Step 4 and Step 5) twice.

For optimal performance, only use sanding belts and discs supplied by BlitzBlade.

SCISSORS:
Inspect scissor and only sharpen the angled cutting edge on each of the blades.

SERRATED KNIVES:
Notice that the back-side of a serrated knife is flat, and only this side should be sharpened. Do not use the guide when sharpening serrated knives. Hold the knife parallel to the moving belt with your free hand, and slide it from side to side. Do not sharpen the curves/teeth of serrated knives.

IMPORTANT

  • Do not push the blade into the belt at a 90-degree angle.
  • Do not touch the moving belt with your fingers.
  • Do not hold the blade in one position only against the moving belt.
  • Do not force the blade hard into the moving belt — unless the blade is damaged and needs reshaping.
  • Forcing the blade will decrease the lifespan of the blade and the belt.
  • Using an incorrect belt grit for your blade type will result in non-sharpening or decreasing the belt or blade’s lifespan.
  • Do not use sanding belts intended for wood (usually red-brown) to sharpen steel or metal blades.
  • The guide should not be in contact with the belt. This will result in damage to the belt and guide.

Changing the belt

1. Loosen the lock knob(1) and tilt the guide (2) away from the belt.

2. Remove the belt guard (3) and belt housing (4) by removing the belt housing knob (5).

3. Release the middle wheel (6) tension by slightly moving and holding the tension handle (7) downward.

4. Remove the abrasive belt.

5. Install and align the new abrasive belt (8) on the lower wheel (9) and upper wheel (10). There is an arrow on the inside of the belt. The arrow should point down in the same direction as the rotation arrow on the housing to avoid belt damage.

6. Release the belt tension handle (7). Spring action will tension the belt when the handle is released.

7. Make sure the belt is tracking correctly. Adjust the tracking if necessary. When the belt is tracking properly, it rides on the centre of each wheel.

8. Replace the belt guard (3), belt housing (4) and re-adjust the guide (1).

How to set the Guide's angle

1. Loosen lock knob (1) slightly until the guide (2) loosens.

2. Adjust the guide to the desired angle. Recommended: 17 – 20-degree

3. Fasten the unit by holding the guide (2) steady with one hand, and tightening the) with the other hand.

Ensure that the guide is NOT in contact with the belt by allowing a gap (3) of ±1 mm when operating. For optimal performance, keep the guide at the same angle for all your blades. Adjust only when a blade with a very different angle, like an axe, needs sharpening.
