The maker is Dirk de Wit from the Netherlands. Only makes a couple per year and has a waiting list for several years. M390 (hardened at a place which also hardens aircraft parts)/vintage German micarta/titanium spring (with an hardened steel insert) and frame. Supersharp and slicy @ 0.35mm at the edge. BL is around 3.5”. Didn’t measure the overall length yet.
Everything is hand made, doesn’t use CNC or watercutting. Just a belt sander, lathe and an old Deckel without any computer)
He did have a knife made by Lionsteel (Grailer I but it has been sold out for a while)
