Claes Blixt, a part-time woodworking teacher, said he is submitting his 62.8-pound butter knife to Guinness World Records in hopes it will be certified as the largest butter knife in the world, The Local.se reported Thursday.
"Big is always fun, everything that is big is fun," Blixt said.
"I just felt I had to let go and dare to make a really big butter knife," he said. "My students think it's hilarious that I'm trying to break the world record."
Blixt said Guinness requires that the knife be usable.
"Of course, ideally I'd have a giant packet of butter and a really big sandwich to prove it with," Blixt said.
