ESEE briefly did a cross collaboration with Ethan Becker for the "ESKBAR" neck knife. Essentially Ethan did a bit of a redesign and his own take on the Izula. If memory suits one inspired the other or vice versa.
Close, but no cigar.

The ESKABAR is a Becker Knife & Tool (KA-BAR) BK-14 and is still available from KA-BAR dealers everywhere. It combines the blade of the Becker Necker (BK 11) with the handle of the ESEE Izula.
