The purpose of this modification is to modify the utility knife so that it does not rattle when closed. This can get very annoying when stored in a pocket and this is a quick, cheap fix.

Step 1: Materials
Other than an Alltrade Quick Change Folding Utility Knife, you will need some craft foam and a Phillips screwdriver. Craft foam is available at nearly every hobby store and is very cheap. I used the sticker kind.
Step Six will require either a drill, or some sandpaper.
Step 2: Dissasemble the Knife
Use your screw driver to unscrew the two screws located in the black handle.
You will be left with the main knife assembly, and a long silver piece.
Step 3: Foam It
Stick a segment of craft foam over the flat part of the silver piece. Firmly press down along the foam, and it should stay on the metal.
Step 4: Sand the Foam Down to Size
I used my dremel along with a small drill bit for this. Although you could use sandpaper, utility knife, etc.
Step 5: Finish the Foam
Use a knife to cut away the foam as shown in the picture. You can either do this before or after applying the foam. I stuck the foam on, then cut the end off. I needed to use some goo gone to get rid of the small sticker residue.
Step 6: Put It Back Together!
Slide the silver piece back into the main assembly and screw it back together.
Step 7: Finished!
Now you have silenced your utility knife. This knife was in the end a great buy. It cost $8 and came with 3 extra blades. The quality is nice and I'd recommend it.
