Hi Gary,
I'm always happy to take another look at an old favourite. You'd never guess it from looking at the knife, but the Vorpal was among the first of Burt's integrals. He's been one of a handful of American makers that has really embraced the genre. Have a peek below at a more current offering: a full integral this time, and a blade almost as long as the entire original Vorpal knife:
And for something you won't likely see anyplace else, check out this laminated (stainless over carbon) integral:
Cheers,
Roger
