CJRB Nanner Folding Knife 3.23in AR-RPM9 Blade - Upswept EDC

In this review the CJRB Nanner folding knife stands out as a compact, design-forward EDC for outdoor and everyday use; its single biggest reason to buy is the upswept blade geometry that aligns the tip with your grip for precise cuts. Designed by Dustin Rhodes, the Nanner blends an unusual blade profile with a lightweight, comfortable G10 handle and a secure crossbar lock, making it particularly useful for camping, hiking and routine cutting tasks where control matters.

Key Features

• Designed by Dustin Rhodes: The upswept blade and closed banana-style handle profile create a natural alignment between tip and grip for controlled, accurate cutting.
• AR-RPM9 Steel Blade: The 3.23in blade with a flat grind and Persian style delivers strong edge retention at HRC59-61 for reliable performance across tasks.
• Crossbar Lock: The sturdy crossbar lock gives stable security and ambidextrous, finger-safe closing for peace of mind during use.
• G10 Handle with Color Accents: The vibrant yellow G10 handle and green spacer/pivot add visual appeal while providing a comfortable, grippy surface.
• Lightweight Carry: At about 67g (2.36oz) and a 4.1in closed length, the Nanner is easy to pocket and convenient for daylong carry.
• Smooth Action: Ceramic ball-bearing pivot construction produces smooth opening and closing for repeatable deployment.

Who It's For

The CJRB Nanner is best for outdoor enthusiasts and EDC users who value an unconventional blade shape that improves tip control for slicing and precision tasks; it suits campers, hikers and anglers who need a compact, lightweight knife with good edge retention. Knife collectors and fans of designer collaborations will also appreciate the distinct look and thoughtful details from Dustin Rhodes.

Those who should look elsewhere include users who prefer a traditional drop-point blade or need a heavyweight tactical folder for heavy pry or baton work; the Nanner is optimized for cutting accuracy and everyday tasks, not brute-force uses.
