I tested the jaw strength of two salvaged clips versus a utility clip bought at a hardware store (38lbs listed clamp strength). Measuring the torque required to produce a 15mm (~1/2 inch) opening, the upcycled clips have satisfactory jaw strength (Table 1). Not bad for free equipment.
Clip #1 (White)
75% @ 15 mm deflection
Clip #2 (Translucent)
36% @ 15 mm deflection
Step 1: Materials and Tools
Waste clothing hanger for pants.
Step 2: Salavaging the Clips
Essentially the hanger is a beam with clips attached to the ends. Use wire cutters to snip through the beam. Preserve the entire body of the clip, retaining the clip's structural integrity.
NOTE: If you simply break off the clip, you will most likely damage one side of the clip, reducing the usefulness and life.
Step 3: That's It
This is just a simple Instructable, but now the idea has been shared.
Although this probably won't change the world, hopefully you find these clips useful. You saved a few dollars and reduced a bit of trash, good karma regardless.
