WeKnife Flight Line LE No. ???/210 Polished Titanium, Hand-Rubbed Satin M390 – limited-edition premium folder with a hand-rubbed satin blade

The WeKnife Flight Line LE No. ???/210 Polished Titanium, Hand-Rubbed Satin M390 folding knife (WE23089-3) is a more collector-oriented version of the Flight Line, produced in a limited series of 210 numbered pieces. It features a Böhler M390 steel blade, hand-satin-finished, a titanium frame with a polished and sandblasted finish, and a Nested Liner Lock. Each knife comes with an individual serial number and a signed certificate of authenticity.

The 96.70 mm blade features a Clip Point profile, a flat grind, and a smooth edge. The hand-satin-finished surface highlights the blade’s geometry and clearly distinguishes this variant from the more utilitarian stonewashed version. A flipper tab enables manual opening, while ceramic ball bearings ensure smooth operation of the mechanism.

Böhler M390 59–61 HRC

The blade is made of Böhler M390 steel with a hardness of 59–61 HRC. The material ensures high resistance to corrosion and wear, as well as excellent edge retention. The flat grind creates a practical geometry that allows the knife to retain its functional character despite its collector’s finish.

Hand-Rubbed Satin and Clip Point Profile

The Clip Point profile ensures a precise tip and a long cutting edge. The hand-rubbed satin finish gives the blade a more exclusive character and highlights the direction of the surface finish, making it one of the most important distinguishing features of this Flight Line version.

Polished Titanium, Nested Liner Lock, and a limited run of 210 pieces

The handle is made of 6Al4V titanium with a polished and sandblasted finish. The Nested Liner Lock stabilizes the blade when open, while ceramic ball bearings in the basket ensure the flipper’s smooth operation. The WE23089-3 variant was produced in a series of 210 individually numbered pieces, each of which comes with a signed certificate of authenticity.

Technical Data

Frequently Asked Questions

How do I care for M390 steel?

After use, clean the blade and dry it thoroughly. M390 is highly corrosion-resistant, but regular care helps keep the surface and edge in good condition.

How do I sharpen an M390 Clip Point blade?

Diamond abrasives work well for sharpening M390. Maintain a consistent angle along the entire length of the edge and apply less pressure near the precision tip.

How does the Nested Liner Lock work?

When opened, the inner liner slides behind the base of the blade and holds it in the open position. Nesting the locking mechanism inside the handle preserves the clean lines of the titanium construction.

How do you clean a titanium handle?

The handle can be gently wiped with a soft, slightly damp cloth and then thoroughly dried. For more refined finishes, it’s best to avoid abrasive materials.

How to maintain ceramic ball bearings?

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