DreamTech D4224LB – 3.74" D2 Folding Knife, Black G10 Handle
The DreamTech D4224LB is the large-frame, black G10 version of DreamTech's D4224 platform. It pairs a 3.74" D2 tool steel blade with a full 5.12" G10 handle and a liner lock, making it a genuinely full-size working folder rather than a pocket knife — 8.86" end to end when open.
D2 is a high-carbon, high-chromium tool steel that holds an edge considerably longer than the budget stainless steels usually found at this price. Hardened to 58–60 HRC, the blade on the DreamTech D4224LB is built for sustained cutting rather than occasional light use.

Frequently Asked Questions
Is D2 good knife steel?
D2 is a high-carbon, high-chromium tool steel with excellent wear resistance, which is why it holds an edge much longer than budget stainless. The trade-off is that it takes more effort to resharpen and it is only semi-stainless, so the blade on the DreamTech D4224LB should be wiped dry after wet or acidic use. At 58–60 HRC it is a strong value choice for an EDC folder.
How big is the DreamTech D4224LB?
The DreamTech D4224LB has a 3.74" blade on a 5.12" handle, measuring 8.86" overall when open. That is the large frame in the D4224 line — if you want the same knife in a more pocketable size, the small-frame version has a 3.27" blade and a 4.25" handle.
How does the liner lock on the DreamTech D4224LB work?
A spring-tensioned steel liner inside the handle slides across the base of the blade once it is fully open, blocking it from closing. To fold the DreamTech D4224LB, push that liner sideways with your thumb and rotate the blade shut, keeping your fingers out of the blade path.
What is G10 and why is it used on the DreamTech D4224LB?
G10 is a laminate of fiberglass cloth and epoxy resin, compressed and cured under heat. It is light, dimensionally stable, completely unaffected by water, and can be textured for grip — which is why the black G10 scales on the DreamTech D4224LB stay secure in wet or gloved hands and will not swell, rot or crack the way natural materials can.
How do you sharpen the DreamTech D4224LB?
Because D2 is wear-resistant, diamond or ceramic stones work far better than soft natural stones. Keep a consistent angle of roughly 20 degrees per side, work through progressively finer grits, and finish by stropping. Maintaining the edge on the DreamTech D4224LB regularly is much easier than restoring one that has been left blunt.
Where can I buy the DreamTech D4224LB?
You can buy the DreamTech D4224LB at Going Gear, an authorized DreamTech dealer. Going Gear has specialized in knives, flashlights and everyday carry gear since 2009 and ships from Georgia.
