Your growing collection deserves serious protection, without taking up your entire desk. The WINARM #30B-K1 is a premium 18-slot compact knife case designed for collectors who value organization and portability.

Housed in a rugged, impact-resistant polypropylene (PP) shell, this mini knife storage case is built to withstand the elements. With an IP67 waterproof and dustproof rating, your folding knives are shielded from moisture, dust, and accidental drops—whether you're at home or on the move.

Precision Storage for 18 Knives

Inside, you'll find 18 precision-cut high-density foam slots. Each slot is sized at 2.3 × 4.5 × 12 cm, providing a snug, scratch-free home for your folding knives up to 15.8 cm in length. The dual-layer protection—combining the bottom foam with a wave-shaped lid pad—ensures your blades never rattle or collide.

Compact Size, Maximum Portability

Weighing only 1.15 kg, the #30B-K1 is highly portable for its 18-knife capacity. Its external dimensions (282 × 240 × 174 mm) make it a great fit for a car trunk, a large gear bag, or neatly stored on a shelf in your home. The ergonomic built-in handle allows you to carry it effortlessly by hand to your next knife show or outdoor trip, providing a space-saving storage solution without the bulk of a larger 60-slot case.

Easy Access with Manual Pressure Valve

Equipped with a manual pressure equalization valve, this case allows you to easily balance internal and external air pressure. Whether you're flying or experiencing temperature changes, you can open the case smoothly without straining, while maintaining a perfect IP67 seal when closed.

Complete Your Collection

WINARM 30B-K1 18 slot compact knife case black hard shell

The WINARM case is equipped with an ergonomic handle for easy transport.

This portable box is made of stainless steel hardware and has an integrally formed handle bracket to effectively prevent damage to the handle during transportation. The box is specially designed with a pressure relief device and a non-destructive installation baffle system, which allows custom panels to be installed without drilling, protecting the waterproof and sealing performance of the box throughout the process.

Why Choose The Winarm Case?

The perfection of every detail is our professional pursuit

Keep your case from sealing shut.
Pressure Release Valve
Changes in altitude, temperature, humidity and geographic location will create a "vacuum environment" that can be effectively sealed by manually adjusting the air valve. WINARM's pressure valve can balance this air pressure difference. Depending on the usage environment, the pressure can be released at any time while preventing water from entering.

Better storage environment
IP67 Waterproof & Dustproof
Not all knife storage is created equal. Cheap knife rolls and flimsy knife cases leave your knives vulnerable to damage, moisture and dust. WinArm knife cases ensure a long-lasting waterproof seal - foolproof!

High-Impact Protection. A fraction of the weight.
Indestructible & Lightweight PP
The WinArm protective case is made of military-grade composite materials, which has excellent impact resistance and extreme lightweight characteristics. The case is thickened with corner anti-collision design, the shock-absorbing structure effectively absorbs impact, and the precision process ensures that every seam and lock can withstand the test of extreme environments. Whether it is humid, hot or cold, WinArm can provide all-weather protection for valuable equipment. The anti-deformation case can withstand repeated use, and the internal buffer system effectively isolates vibration and shock.

Close with confidence. Open with ease.
Latching System
This WINARM organizer features a heavy-duty locking system that uses spring force and dual action to clamp the box securely, keeping your small gear protected from the elements. Prevents the box from opening during transport or if dropped. Super-tough nylon construction and stainless steel hardware ensure your important items stay safe in the WINARM waterproof organizer, no matter where you are.
