DreamTech D4260CBL – 4.25" Satin M390 Drop Point Folding Knife, Cryogenic Titanium Handle
The DreamTech D4260CBL is the cryogenic-titanium version of the D4260: a 4.25" satin M390 drop point blade on a button lock, in a handle that has been cryogenically treated to bring out a deep, variegated colour in the titanium. It is a large folder — 7.32" overall on a 3.07" handle — and the blade steel is genuinely premium.
M390 is a Bohler powder-metallurgy stainless running very high chromium and vanadium. Hardened here to 60–62 HRC, it holds an edge dramatically longer than D2 or 14C28N while staying fully stainless.

Frequently Asked Questions
What is a cryogenic titanium handle?
Cryogenic treatment takes the titanium down to very low temperature as part of finishing, which alters the surface oxide and produces deep, variegated colouring that is part of the metal rather than a coating. The handle on the DreamTech D4260CBL therefore cannot chip or peel the way an anodised or painted finish can, and each one varies slightly.
Is M390 good knife steel?
M390 is one of the best production blade steels available. It is a Bohler powder-metallurgy stainless with high chromium and vanadium, giving outstanding edge retention and full corrosion resistance. On the DreamTech D4260CBL at 60–62 HRC it will hold a working edge far longer than D2 — the trade-off is that it needs diamond stones to resharpen.
How does the button lock on the DreamTech D4260CBL work?
A spring-loaded button in the handle drops into a detent on the blade tang when it swings fully open, locking it there. Press the button to release and the blade folds. It makes the DreamTech D4260CBL genuinely one-handed to open and close, and keeps your fingers clear of the blade path.
How big is the DreamTech D4260CBL?
The DreamTech D4260CBL carries a 4.25" blade and measures 7.32" overall. That is a large folder, well past everyday-carry size in many jurisdictions — check your local blade-length laws before carrying it.
How do you sharpen the DreamTech D4260CBL?
M390's vanadium carbides are harder than standard ceramic abrasives, so use diamond stones. Hold roughly 20 degrees per side and work through progressively finer grits. The edge on the DreamTech D4260CBL needs sharpening far less often than a D2 blade, but when it does, diamond is the tool.
