Look Sharp, Stay Sharp
Inspired by traditional Viking stone sharpeners, this patented pendant-style whetstone modernizes a centuries-old tool for everyday carry. These hand-selected stones feature four unique grinds, allowing you to hone knives, tools, and gear on the go, while doubling as a stylish accessory.
Quick Start
Get to know your Viking Whetstone Necklace before you put it to work.
- Wear it as an everyday necklace, keeping a genuine sharpening stone always within reach.
- Use the pendant’s four functional grinds – flat surface, rounded edge, beveled edge, and hook groove – to sharpen everything from knives and axes to fishhooks and gouges.
- Simply add a little water or saliva to the stone for smoother sharpening and less clogging.
- Practice on a few blades at home to feel how the stone cuts before you need it in the field.
Features & Functions
Wearable Tool – Genuine Arkansas Novaculite stone doubles as a sharp-looking pendant necklace.
Four Functional Grinds – Expertly cut whetstone includes a rounded edge, beveled edge, hook groove, and flat lap, sharpen everything from hooks and saws to blades and gouges.
Medium Grit (600–800 equiv.) – Ideal for restoring working edges without over-refining.
Unique Stone Patterns – Each pendant has natural color variations (white, grey, speckled, or rare tones like pink and blue) that deepen when wet.
Handmade in the USA – Every stone is hand-cut for heirloom quality and lasting durability.
Care & Safety
- Keep It Clean: Rinse lightly after sharpening to clear metal filings; allow it to dry fully before storing.
- Stone Durability: Arkansas Novaculite is tough but natural; avoid dropping it on hard surfaces to prevent chips.
- Sharpen Responsibly: Use light, controlled strokes; let the stone do the work rather than forcing pressure.
- Cord Maintenance: Rinse the leather cord occasionally and condition it with leather oil if it starts to dry out.
- Expect Variations: Color and pattern changes are natural and part of the stone’s character; they even become more vivid when wet.
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.
