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.
