I picked up a pack of 5 X Acto blades- number 11- for fifty cents at a flea market, and being that I do not own an actual x acto knife, I made one out of a toothbrush.
This is my first Instructable, I apologize for not having pictures for all the steps, making this into an Instructable was an afterthought, hope it still helps someone.
Please leave questions and comments.
Step 1: What you'll need
drill with bits
needle nose pliers
fire- stove, blowtorch or lighter
X Acto blades
breathing mask or respirator (fumes from melted toothbrush are unpleasant)
Step 2: Decapitate the toothbrush
Step 3: Start making the hole for the blade
sorry no pictures of this
Step 4: Prep the blade for insertion
Step 5: Inserting the blade
while the plastic is still warm and malleable, use the pliers to crimp the edges so the plastic will harden tightly around the blade.
Step 6: Finishing touches
Optional- put a few drops of super glue into the hole before putting the screw in, it'll make it a bit stronger.
