Step 1: Parts

There are only 3 simple parts for this hack.

part 1: small screwdriver

part 2: small pencil sharpener (found cheep at dollar store).

part 3: exacto-knife.

Step 2:

Next get out your pencil sharpener and your screwdriver.

Then unscrew the small screw on the blade and carefully remove it. it is up to you if you want to keep the housing

and screw because all we are looking for is the blade.

Now that you have the blade get your knife. this next part is simple. remove the blade and carefully insert the new blade and tighten.
