Bestech CIRCUIT BG35B-2 – EDC Folder with K110 Grey PVD Blade, Grey G10 Handle, and Titanium Clip
The Bestech CIRCUIT BG35B-2 is a refined, monochromatic EDC folding knife designed in-house by Bestech Knives. Its 3.23" K110 tool steel blade with a grey PVD coating pairs with matching grey G10 handle scales and a titanium pocket clip for a coherent all-grey aesthetic that is as functional as it looks. At 101g with a 4.33" closed length, the CIRCUIT BG35B-2 carries comfortably and deploys smoothly via ceramic ball bearings at the pivot. The Liner Lock provides dependable retention throughout daily use.

Design & Materials
The CIRCUIT BG35B-2 is built around a deliberate design philosophy: coherent material choices and a consistent grey palette from blade to clip. K110 is Böhler's high-carbon, high-chromium tool steel — the Austrian equivalent of D2 — with a chemical composition that delivers exceptional edge retention and wear resistance. The grey PVD coating over the K110 blade provides corrosion resistance and low-visibility appearance while maintaining a hard, durable surface that is straightforward to maintain.
Grey G10 handle scales reinforce the monochromatic character of the CIRCUIT. G10 is a glass-fiber reinforced epoxy composite that resists moisture, temperature extremes, and oils — an ideal handle material for everyday carry in varied conditions. The titanium pocket clip is a notable upgrade over the steel clips common on most G10 knives at this price point: titanium is lighter than steel and corrosion-proof, adding a premium touch without adding weight.
At 101g, the CIRCUIT BG35B-2 is meaningfully lighter than comparably sized D2 or K110 G10 folders, largely due to the titanium clip and refined construction. The ceramic ball bearing pivot provides smooth, consistent blade deployment that holds up over repeated use. The overall result is a well-balanced, low-profile everyday carry knife with no unnecessary visual clutter and no weak material choices.
K110 Steel — Böhler's Tool Steel Standard
K110 is manufactured by Böhler, the Austrian steel maker, and is the European equivalent of D2 tool steel — sharing nearly the same alloy composition of approximately 1.55% carbon and 11.5% chromium. Like D2, K110 is a semi-stainless tool steel: the chromium content is sufficient for good corrosion resistance in typical use, but it is not fully stainless and benefits from routine drying and occasional light oiling. The high carbon content gives K110 outstanding edge retention and wear resistance that outperforms standard stainless steels. On the CIRCUIT BG35B-2, the grey PVD coating adds an additional barrier against corrosion on the blade flats.
Liner Lock Mechanism
The CIRCUIT BG35B-2 uses a Liner Lock. When the blade is fully opened, a steel liner inside the handle springs behind the blade tang, locking it in the open position. To close, press the liner aside with your thumb and fold the blade back into the handle. The Liner Lock provides automatic, positive lockup with no secondary action required on deployment.
Frequently Asked Questions
What steel is the Bestech CIRCUIT BG35B-2?
The Bestech CIRCUIT BG35B-2 uses K110 tool steel with a grey PVD coating. K110 is Böhler's high-carbon, high-chromium tool steel — the Austrian equivalent of D2 — known for exceptional edge retention and wear resistance. The grey PVD coating provides corrosion resistance and a uniform grey appearance across the blade flats.
What is K110 steel and how does it compare to D2?
K110 and D2 are functionally equivalent high-carbon, high-chromium tool steels. K110 is produced by Böhler in Austria; D2 originated in the United States. Both contain approximately 1.55% carbon and 11.5% chromium, which delivers the same core characteristics: excellent edge retention, high wear resistance, and semi-stainless corrosion resistance. Some knife enthusiasts specifically seek K110 for its Böhler origin and slightly tighter manufacturing tolerances. On the Bestech CIRCUIT BG35B-2, the grey PVD coating over K110 adds an additional layer of corrosion protection beyond what the steel alone provides.
What is the blade length of the Bestech CIRCUIT BG35B-2?
The Bestech CIRCUIT BG35B-2 has a blade length of 3.23" (82mm) and an overall open length of 7.56" (192mm). The closed length is 4.33" (110mm).
Why does the Bestech CIRCUIT BG35B-2 have a titanium clip?
The titanium pocket clip on the Bestech CIRCUIT BG35B-2 is an upgrade over the steel clips found on most production G10 folders at this price point. Titanium is lighter than steel and fully corrosion-proof, contributing to the CIRCUIT's lighter overall weight of 101g while adding a premium component. It also matches the grey-on-grey aesthetic of the knife's blade and handle.
What lock does the Bestech CIRCUIT BG35B-2 use?
The Bestech CIRCUIT BG35B-2 uses a Liner Lock. The steel liner inside the handle springs automatically behind the blade tang when the knife is fully opened, providing positive lockup. To close, press the liner aside and fold the blade back into the handle.
Who designed the Bestech CIRCUIT BG35B-2?
The Bestech CIRCUIT BG35B-2 was designed in-house by Bestech Knives, representing the brand's vision for a refined, monochromatic EDC folder built around a K110 grey PVD blade and matching grey G10 handle with a titanium pocket clip.
How much does the Bestech CIRCUIT BG35B-2 weigh?
The Bestech CIRCUIT BG35B-2 weighs 101g — relatively light for a 3.23" G10 folder of its overall size, thanks in part to the titanium pocket clip and refined construction.
Where can I buy the Bestech CIRCUIT BG35B-2?
The Bestech CIRCUIT BG35B-2 is available at Going Gear, an authorized Bestech Knives dealer offering genuine Bestech products with shipping across the United States.
