Boker Plus Coffin Hidden Release Bolster Release OTS Auto Black G10-14C28N Blade AUBK01BP0170

Bold in design and modern in execution, the Boker Plus Coffin Hidden Release OTS Auto brings a distinctive silhouette and fast, intuitive deployment together in a rugged everyday carry platform. Built for users who appreciate unique styling paired with dependable automatic performance, this out-the-side automatic knife delivers both visual character and functional reliability in a compact, hard-use design.

At the core of the knife is a 3.23-inch blade crafted from 14C28N stainless steel. Known for its excellent balance of edge retention, corrosion resistance, and ease of maintenance, 14C28N is a high-performance steel well-suited for everyday carry applications. It delivers smooth, consistent cutting performance across a wide range of tasks, from routine utility work to more demanding cutting needs. The blade geometry is designed for practical efficiency, offering controlled slicing performance and dependable durability in daily use. Finished to complement the knife’s overall aesthetic, the blade maintains a clean, functional appearance that matches its purpose-driven build.

What sets this model apart is its bolster release automatic mechanism. Integrated directly into the handle design, the bolster release system allows the blade to deploy with a natural, fluid motion. A simple press of the bolster activates the mechanism, sending the blade smoothly out the side of the handle and locking it securely into place. This hidden release design keeps the knife’s profile clean and streamlined while offering fast, one-handed access when it matters most. The lockup is solid and confidence-inspiring, ensuring stability during use.

The black G10 handle provides a strong, lightweight foundation built for durability and control. G10 is widely respected for its toughness, resistance to moisture, and excellent grip characteristics, making it a reliable choice for demanding everyday carry environments. The textured surface enhances traction, while the ergonomic shaping ensures a secure and comfortable hold. The all-black finish reinforces the knife’s understated, tactical aesthetic while maintaining a cohesive, modern appearance.

Weighing 4 ounces, the Coffin OTS Auto strikes a balanced feel in hand—substantial enough for control, yet compact enough for comfortable pocket carry. Its design emphasizes both function and form, with clean lines and a distinctive coffin-style profile that sets it apart from conventional automatics.

Built in the US under Boker Plus standards, this model reflects a commitment to quality construction and innovative design. It’s a knife made for users who want something beyond the ordinary—something that performs as well as it stands out.

The Boker Plus Coffin Hidden Release OTS Auto combines a black G10 handle and 14C28N blade with bolster-release automatic action for fast deployment, rugged durability, and standout everyday carry performance.
