Bestechman Sprite Dark Grey Titanium, Dark Bead Blast Stonewashed M390 – a compact premium folding knife with a dark finish
The Bestechman Sprite Dark Grey Titanium, Dark Bead Blast Stonewashed M390 (BMK21D) folding knife is a subdued, technical variant of the compact Sprite. The Böhler M390 steel blade is paired with a titanium handle in a dark gray finish and a Dark Bead Blast Stonewashed surface.
The model weighs 60.00 g and has a total length of just 142.00 mm. The 60.00 mm Drop Point blade, flat grind, B-Lock, and ceramic Ball bearings come together to create a small yet structurally advanced EDC folder.
M390 62 HRC – Premium Steel in a Compact Format
Böhler M390, with a hardness of 62 HRC, offers high resistance to wear and corrosion, as well as long-lasting edge retention. This is one of the main reasons why the Sprite stands out as a compact premium knife.
Dark Bead Blast Stonewashed
The dark bead-blasted finish combined with stonewashing gives the blade and handle a cohesive, technical look. The overall design remains understated and complements the Sprite’s minimalist format well.
Dark Grey Titanium and B-Lock
The titanium handle remains lightweight while offering a solid construction. The B-Lock can be operated from both sides, and the reversible deep-carry clip makes it easy to adjust the carrying style to the user’s preferences.
