We Could Not Break the Unbreakable Shoelaces

Rhino Laces claim to be unbreakable. Made for smokejumpers who need to lace up, they are supposed to be uncuttable, unchoppable, fireproof. We took this marketing strategy as a challenge, so we tried to break them. They broke us.

We tried the Fiskars on the Rhinos. Not a flicker. The Gerber River Shorty didn't move the needle either.


The SOG Bladelight did nothing but risk our lives. Nothing doing. It did, however, reveal the secret behind the Rhinos—they have a core of what appears to be steel cables. Valyrian steel, probably. Or adamantium.

We couldn't find a truck with a hitch to try to tow something devastatingly heavy, but I can confirm a tensile strength of at least 172 pounds.

Since these are purpose-built for woodland firefighters, we did not expect a BIC to do much. It didn't. After putting the Rhinos through this barrage of tests, we have to agree with the packaging. They are the toughest laces we've ever seen.
