find your perfect grind

Not matter your preferred blade or hook, there's a grind on this stone to hone everyones' favorite tool.

Choose from a Rounded Edge, Beveled Edge, Hook Groove, or Flat Lap to sharpen everything from seatbelt and fingernail cutters to small serrations and spearpoints.

This whetstone sharpener can do it all.

The history & evolution of a whetstone pendant

Keeping knives and tools sharp while out in the field has been an issue ever since blades were first carried. The solution to this problem dates back over 1000 years, to when Iron Age Vikings introduced a compact sharpening stone that could be tied to the body and taken into the field. This ancient but tried and true tool has become our modern-day whetstone.

Great company that stands behind great products

Very good. I received one Spark that didn’t seem to be the right rare variety and they immediately made good and sent me a new one that was what I expected. No questions or hassles or anything. Am enjoying using the Viking Spark. It works surprisingly well as a fire starter and it’s nice to have a small but very decent Arkansas stone handy to touch up my knives. Also looks great.

Great piece of kit

I had a viking whetstone necklace before, I ended up losing it... This was a great replacement I haven't had a chance to use the ferro rod yet, but the clasp is way better than the 2 knots on the older whetstone necklaces.

Seems good

I have not used it in the field yet but it does spark and I touched up a few knives. It looks pretty cool and is small enough to consider taking it rather than leaving it when considering weight. I’m looking forward to getting it outside!

Frequently Asked Questions

What is the Viking Spark™?

A stylish, wearable accessory that combines the capabilities of our fire-starting and tool-sharpening necklaces into one streamlined pendant.

How do I use the Viking Spark™ to start a fire?

Slide the ferro rod down the leather cord and deploy the ceramic from behind the whetstone. With the ferro rod braced securely in one hand and the ceramic pinched firmly in the other, scrape the edge of the ceramic down the length of the ferro rod to shower sparks onto your tinder.

What materials are used to make the Viking Spark™?

The stone itself is Arkansas Novaculte, one of the most renowned sharpening stones in the world. The ceramic is Zirconia, one of the hardest man-made materials in existence. The toggle is ferrocerium, an impressive compound that our ancestors likely would have killed for. And it’s all brought together by a genuine cowhide leather cord, making a necklace that, like you, only gets better with age.

Can the Viking Spark™ be worn during physical activities or in wet conditions?

Absolutely! Rain, snow, swimming, even showering is fair game. Wear it like any other waterproof necklace but give it a quick rinse after sweating or exposure to salt water to protect the ferro rod from corrosion.

Do I use water or oil while using the whetstone?

Either. It will naturally absorb oils from your skin but you can also use water to build up a slurry that further aids in the sharpening process.

Can I travel with the Viking Spark™?

As of this writing, there are no TSA restrictions against flying with a Viking Spark™. Keep in mind, however, that it is always up to the TSA agent on duty that day. We recommend checking current TSA regulations before flying.

How can I keep the leather soft?

Actually, the best thing to do is wear it - it will absorb natural oils from your skin and keep it well conditioned. If it does start to dry out at any point, simply give it a coat of your favorite leather conditioner.
