I contacted Kershaw about the broken torsion bar on my Blur, and Brittany at Kershaw Customer Service told me they’d send me a replacement for free. She also said to send the knife in for a free warranty repair if I had any problems.
Torsion bar arrived in the mail yesterday, took about five minutes to install, and now the Blur is restored to proper *snikt*-ness. So thanks, Kershaw, for backing up your products with great customer service. Mad props, or whatever the kids say these days.
