Bestechman Sprite Black-Green G10, Black Stonewashed M390 – an ultralight, compact folding knife made of M390
The Bestechman Sprite Black-Green G10, Black Stonewashed M390 folding knife (BMK21F) is an ultralight EDC folding knife weighing just 45.00 g. It combines high-grade Böhler M390 steel with a black-and-green G10 handle, a B-Lock locking mechanism, and a very compact 60.00 mm blade.
The black stonewashed finish gives the blade a subdued, utilitarian look. The Drop Point profile, flat grind, thumb studs on both sides, and ceramic ball bearings create a practical set for everyday carry in an exceptionally lightweight form.
M390 61 HRC and only 45 g in weight
Böhler M390, hardened to 61 HRC, ensures high resistance to corrosion and wear. Combined with the G10 handle, this results in a folding knife weighing just 45.00 g, without compromising on the high-quality blade material.
Black Stonewashed and flat grind
The dark stonewashed finish complements the black-and-green handle well. The Drop Point profile and flat grind provide practical geometry for a lightweight EDC.
Black-Green G10 and double-sided B-Lock
The Black-Green G10 handle keeps the weight low and withstands daily use well. The B-Lock can be operated from both sides, as can the reversible deep-carry clip, which increases the design’s versatility.

Frequently Asked Questions
How do I care for M390 steel?
After use, clean the blade and dry it thoroughly. Regular care helps keep the edge and surface in good condition for a long time.
How do you sharpen an M390 steel Drop Point blade?
It’s best to use high-performance abrasives, especially diamond ones, and maintain a consistent sharpening angle along the entire length of the edge.
How does the B-Lock work?
The crossbar stabilizes the blade when open and allows for convenient release of the lock from either side of the Handle.
How do you clean Black-Green G10 Handle?
The Handle can be cleaned with a soft brush or a damp cloth and mild detergent. Be sure to dry it thoroughly after cleaning.
How to maintain ceramic ball bearings?
The area around the pivot should be regularly cleaned of dust and debris. If the mechanism begins to operate less smoothly, you can apply a small amount of a light lubricant designed for folding knives.
