Böker Plus Extension Knife: Compact Carry, Full‑Size Control — SHOT Show 2026

The Böker Plus Extension Knife is possibly the weirdest knife I’ve ever seen. It’s like the guys who made G.I. Joes and Transformers in the 1980s made a full-size blade.

Designed by Hein, it appears to be a chunky, belt knife with a full tang 4.7″ clip point profile. What sets it apart is the extendable blade design. Press a button, and the handle flips end for end, doubling the exposed blade length. It’s more than meets the eye.

Now it’s a kukuri-ish profile blade, 7.3″ long, and ready for all kinds of bushcraft work. It’s made with D2 steel that is reasonably tough and edge-retaining.

It’s long enough for chopping and splitting kindling, but folds away to fit in the short sheath. Böker reports that it’s inspired by medieval Baselard swords, and the handle does seem to have a hilt.

This blade is wacky, but it’s certainly not kitchy. It locks up tight and seems well-made.

Who’s the Böker Plus Extension Knife for? Maybe for actual bushcraft use.

The short mode is a decent shape for processing carcasses, while the extended mode could help you win a reality TV show. If you’re into knives, this one deserves a look. It’ll be available in May, 2026 for $259.
