THE FOUR GRINDS
HOW-TO RE-SIZE YOUR NECKLACE
- Put the necklace on with the clasp unclipped. Adjust the pendant to hang at your desired location.
- Have a buddy stand behind you and hold both ends of the necklace around the back of your neck with the ends overlapping.
- Note where the ends overlap. Mark, measure, or make a really, really, really good mental note of excess on ends. The average person cuts 2-3” off each end.
- Use a sharp knife or scissors to cut the necklace (≈45°) at the desired length. (See Video) Remember to "measure thrice, cut once" to avoid making a mistake. The clasp will add about 3/4” or 2cm back to the circumference, which is probably a good safety margin to leave.
- Attach the clasp to the end of the necklace. (See Video)
- Try on the necklace to ensure it fits comfortably and repeat the process if needed.

Can I wear the Viking Spark™ in the shower, lake, ocean, and/or pool?

Salt water and sweat can corrode the Ferro Rod after an extended amount of time, so be sure to rinse the necklace with fresh water and move the ferrocerium rod up and down the leather to remove residue from all parts of the necklace.
How do I care for the leather cord?
Rinse your necklace in fresh water weekly to wash off oils and salts, sliding the toggle up to clean around the knots.
If the leather looks dry, apply a small amount of Obenauf’s Heavy Duty LP leather conditioner to keep it supple.
