Understanding the Boker Plus Kwaiken

Designed by Lucas Burnley, the Boker Plus Kwaiken series blends minimalistic Japanese aesthetics with high-performance materials like titanium and VG-10 steel. These knives are known for their slim profiles and exceptionally smooth ball-bearing flipper action.

What steel is used in the Boker Plus Kwaiken series?
The Boker Plus Kwaiken series features high-performance steels including VG-10, D2, and S35VN, with some premium models utilizing MagnaCut. The Kwaiken Air variants typically use VG-10 for its excellent corrosion resistance and ease of sharpening, often finished with either a sleek satin or a durable black coating.
Why is the Boker Plus Kwaiken so popular?
The Boker Plus Kwaiken is considered a cornerstone of the Boker Plus lineup because it offers a custom-level design from Lucas Burnley at an accessible price range. Its sleek, narrow profile allows it to function as a highly capable tool that still fits the aesthetic of gentleman's pocketknives.
What is the difference between the Kwaiken Air and the standard models?
The Kwaiken Air is a lightweight evolution of the original design, featuring a thinner profile and reduced weight for effortless everyday carry. While many folders use stainless steel liners, the Kwaiken Air often utilizes titanium liners to shave off weight without compromising the structural integrity of the liner lock.
How does the flipping action feel on these knives?
The Boker Plus Kwaiken series is equipped with ball bearings in the pivot, providing a fast and consistent flipping action. This mechanical setup ensures the blade deploys smoothly with a light press on the flipper tab, which is designed to remain low-profile when the knife is closed.
What handle materials are available for the Kwaiken series?
The Boker Plus Kwaiken is available in a wide variety of handle materials, ranging from traditional Cocobolo wood and Micarta to modern G10 and stonewashed titanium. This variety allows users to choose between a classic, organic feel or a more technical, high-grip surface depending on their preference. You can browse the full range of options in the Boker Knives collection.
