The Complete Bestech Knives Senu Series Model Breakdown

When custom knife designer Grzegorz Grabarski (widely known as Kombou) collaborates with Bestech Knives, the result is always a striking blend of avant-garde design and precision manufacturing. The Bestech Senu series is a prime example of this partnership. Taking visual cues from the sharp, aerodynamic lines of a soaring eagle, the Senu features a futuristic, highly architectural footprint that stands out instantly in any everyday carry (EDC) collection.

However, navigating the premium folder market can be tricky when a single design spans multiple model numbers. Bestech often releases a model family sharing the same physical chassis but featuring radically different blade steels, handle textures, and colorways. To help you find the exact version that fits your style and cutting needs, this guide provides a complete, model-by-model breakdown of the Bestech Senu series.

Shared Architecture: The Senu Blueprint

Before diving into the unique characteristics of each specific model code, it is helpful to look at the baseline engineering dimensions that form the foundation of every knife in the Senu lineup:

• Overall Length: 7.96 inches (202.3 mm)

• Blade Length: 3.48 inches (88.4 mm)

• Blade Thickness: 0.13 inches (3.3 mm)

• Blade Profile: Drop Point with a high Flat Grind

• Handle Length: 4.48 inches (113.9 mm)

• Frame Material: 6AL4V Titanium with internal weight relief milling

• Pivot System: Caged Ceramic Ball Bearings

• Locking System: Titanium Frame Lock with Hardened Steel Insert

• Weight: ~3.81 ounces (108 grams)

Every model features a smooth dual-deployment system. You can open the blade instantly via the snappy, low-profile flipper tab, or opt for a controlled manual rollout or reverse middle-finger flick using the clean, elongated thumb hole cutout.
