What you might not be able to see is that this take borrows some inspiration from the brand’s SP model. That means this version is much slimmer and lighter, weighing just 3.7 ounces (compared to the ATB and AT’s 4.4-ounce weight).

But here’s the real kicker: those changes to its weight and girth come without compromises elsewhere; you’ll get the benefits of the refinement without sacrifice. The construction is as rock-solid as ever, and the materials are absolutely stellar.

Guaranteed rustproof for life

The Invictus-ATBSP is offered in four configurations — three that differ only in their colors, alongside one with a slightly more expensive material swap.

For all four, the base of the handle is made from tough, lightweight titanium (which is naturally rustproof). That includes its formidable frame lock. They also all come with a ceramic ball bearing pivot for smooth, quick deployment.
