ineffable. can't be effed.
This one gets screwed up a lot, even by people who should know better.
HTH. Happy Friday.
But as your table shows, Vise-Grip is a Trademark. Kobalt can't infringe on that exact name, but they can name their similar product with a name that sounds the same so people understand what they're buying. :)-slonkak
Yeah, I almost put something in the post about that. Since the purpose of trademark protection is to prevent consumer confusion, I doubt that Lowes/Kobalt would be on solid legal ground by using a homophonous name for their tool. I'm going with the "some data loader f'd up, used a trademark he shouldn't, and accidentally misspelled it" hypothesis.
