Bestechman Curvee Black G10, Stonewashed/Satin AEB-L by Ostap Hel – a lightweight EDC folding knife with smooth ergonomics

The Bestechman Curvee Black G10, Stonewashed/Satin AEB-L folding knife by Ostap Hel (BMK20A) is a lightweight EDC folder designed by Ostap Hel. The slim design, weighing 84.00 g, features an AEB-L steel blade, a black G10 handle, a Liner Lock, and two methods of manual opening.

The 87.50 mm blade features a Drop Point profile, a flat grind, and a smooth edge. The combination of stonewashed and machine-satin-finished surfaces gives it a distinctive yet functional character, while ceramic ball bearings ensure smooth operation of the mechanism.

AEB-L 61–62 HRC and Cryogenic Treatment

The blade is made of AEB-L steel, hardened to 61–62 HRC. The manufacturer also applies cryogenic treatment to ensure a stable steel structure and good performance characteristics. The flat grind provides a versatile geometry for everyday cutting.

Drop Point and two-tone finish

The Drop Point profile offers a well-controlled tip and a practical cutting edge. The combination of stonewashed and machine-satin finishes highlights the blade’s geometry and complements the minimalist character of the design.

Black G10, two opening mechanisms, and deep carry

The black G10 handle features the smoothly rounded lines characteristic of Ostap Hel’s designs. The blade can be opened using the front flipper or thumb studs, and the steel deep-carry clip can be repositioned to the right or left side. Ceramic ball bearings ensure light and smooth blade operation.

Technical data

Frequently Asked Questions

How do I care for AEB-L steel?

After use, clean the blade and dry it thoroughly. For long-term storage, you can apply a thin layer of a knife-specific preservative.

How do I sharpen a Drop Point blade?

It’s best to sharpen the smooth edge while maintaining a consistent angle and even pressure. Work more gently near the tip to preserve its original geometry.

How does the Liner Lock work?

When opened, the spring-loaded liner slides behind the base of the blade and holds it in the open position. Pushing the locking element back allows you to close the knife safely.

How do you clean a G10 handle?

G10 can be cleaned with a soft brush or a damp cloth and mild detergent. After cleaning, the handle and the area around the mechanism should be thoroughly dried.

How to maintain ceramic ball bearings?

The area around the pivot should be regularly cleaned of dust and debris. If necessary, you can apply a small amount of a light lubricant designed for folding knives.
