I've seen letter openers in stores for years, but I never felt like dropping the money to get one. When I recently came into possession of some extra stock of Duane Reade club cards, I knew I had my chance!
Step 1: Materials
Laser Cutter, X-Acto knife or Scissors.
A few minutes to spare.
Step 2: Template
One thing I learned while making these, having a long skinny edge doesn't work. I find that a short, thin at the end point, works best - see pictures for more details.
Draw a template on your card, or in whatever program you plan to use to laser cut with.
If you're using the laser cutter, I'd recommend creating a template for the card that you can use to ensure you have it situated in the correct space when you laser etch. You can use cardboard or some scrap acrylic for this purpose.
Step 3: Cut
Step 4: Prep X-Acto Blade
- Grab the X-Acto blade firmly between two pairs of pliers.
- Slowly bend the X-Acto blade in half.
- You should have half of the X-Acto blade in each pair of pliers when it snaps (it doesn't take much bend to snap it).
Step 5: Attach Blade
Grab some clear tape, and tape the X-Acto blade in place.
If you're worried that someone might cut themselves, grab another card and sandwich the X-Acto blade between them.
