Step 1

Remove the tray from the front of the pencil sharpener and empty the pencil shavings.
Make sure the pencil sharpener is unplugged!

The screwdriver must be 6” long to reach the two screws in the front of the sharpener.

Step 3

Lift the motor and cutter from the top case of the sharpener.
Carefully move the wires so that the case can be completely removed.
You shouldn’t have to disconnect any wires to take the case off. If so, contact the manufacturer.

Make sure to hold the cutter to keep it from rotating.

WD-40 would be helpful, but not necessary.

Great instructions on replacing the sharpener. My father took the model 18 apart but failed to document with pictures on the step by step breakdown. I'm left with out a crucial part of the re- installment. The question is in step 7, the piece right behind and below the screw driver is a plastic piece with two wires comming out of it. where does this piece fit? any help or redirection to a site that might have this info. direct reply at

tah33 - that part is the switch that senses the pencil to turn on power. There is a plastic piece that goes over the top of the cutting mechanism to help guide all the shavings down into the shavings tray. The switch goes onto the front of that piece. If you look at step 4 it shows the switch mounted to the piece I am talking about, Randy (the author) calls it the protective case.

Steps 5 and 6 are not required.

The wire nuts were loose and came off, is there a way to know for certain which wires go together?

The link to purchase a new cutting blade brings you to Amazon, and it's not available. Any other place that FOR sure the part is available?

My question is similar to tah33's and David Ryan reply back in 2017/2018. Unfortunately, in our case, the wires came out of the housing that David talked about in his reply. Is there any way to know how to put that back together?
