Safety Technology Stainless Steel Butterfly Knife with Tactical Handle Cutouts – 4″ Straight Back Blade, 9″ Overall, Latch Safety, Lightweight Flip Design, 3 Finishes

Balanced Construction for Flipping, Solid Enough for Everyday Use

The straight back blade geometry on this knife keeps the spine flat and the edge curved upward toward the tip — a practical cutting profile that works well for slicing tasks and gives the blade a clean, uncluttered look. At 9 inches overall and 0.35 lbs, it’s lighter than full-metal balisongs built for display, and the tactical handle cutouts are part of why. Removing material from the handle reduces weight at the ends of the handles, which affects the rotation dynamics when flipping. The latch engages cleanly and the handle surface is smooth without being slippery.

Who This Butterfly Knife Is For

This knife suits people who want a functional butterfly knife for flipping practice and everyday carry where permitted. The 9-inch overall length and 4-inch blade hit a practical middle ground — substantial enough to use, compact enough relative to larger balisongs to carry more comfortably.

It’s also a reasonable entry point for people new to butterfly knives who want to learn basic flip techniques on a real knife before investing in a premium balisong. The balanced handle cutout design gives consistent feedback through rotations, which helps with learning proper technique. Collectors adding a lighter-weight option alongside heavier all-metal pieces will find the three finish options useful for visual variety.

How the Blade and Handle Design Work Together

The straight back blade profile keeps the spine of the blade level while the cutting edge sweeps upward toward the tip. This geometry creates a longer usable cutting edge compared to drop-point or clip-point designs of the same blade length, and the angled tip improves piercing capability. For a butterfly knife used in utility tasks, this means the blade works effectively across a wider range of cutting motions.

The handle cutouts serve a mechanical purpose beyond aesthetics. By removing material from the stainless steel handles, the manufacturer reduces the rotational inertia at the handle ends — the weight that must be overcome and controlled during a flip. The result is a knife that responds more crisply to wrist movements and requires less force to rotate than a fully solid handle. The smooth handle surface, combined with the reduced weight, makes extended flipping practice less fatiguing.

The latch mechanism locks both handle halves together when the knife is folded closed. This prevents the handles from spreading open during storage, transport, or when the knife is clipped or carried in a bag. Always engage the latch when the knife isn’t in active use.

Practical Details

Overall length is 9 inches with a 4-inch straight back blade. Weighs 0.35 lbs — the lightest knife in this group. Handle material is stainless steel with tactical cutouts and smooth surface finish. Latch safety included. Available in three finishes: Black, Plasma, and Stainless Steel. As with all butterfly knives, check your state and local laws before purchasing — regulations vary widely across jurisdictions.

A lightweight, well-balanced butterfly knife with a practical straight back blade — built for flipping performance without sacrificing everyday utility.
