Pro-Tech TR-4 - Blue Feather Textured Aluminum - Stonewashed MagnaMax Blade

MagnaMax Button Lock with Aluminum Handles

The Pro-Tech TR-4 is a full-size folder built for users who want fast, one-handed deployment paired with premium materials. This Blue Feather Textured version pairs a durable aluminum handle with a high-performance blade steel, making it a strong choice for everyday carry or collection.

Blade

The 4" drop point blade is made from MagnaMax steel with a stonewash finish. MagnaMax is a premium steel prized for its excellent edge retention, high toughness, and strong corrosion resistance, making it well suited to hard daily use. The stonewash finish hides scratches and wear while giving the blade a rugged, low-maintenance look.

Handle

The handle is machined aluminum with a textured Blue Feather pattern for grip and visual depth. Aluminum is lightweight yet rigid, keeping the knife durable without adding bulk. At 5.3oz, the TR-4 carries substantially but remains manageable for daily use.

Carry

The TR-4 uses a button lock, allowing quick blade deployment and release with a single press of the firing button. This is a manual knife - the blade must be opened by hand despite the fast-action mechanism. A right-side, tip-up pocket clip keeps the knife accessible and oriented for a quick draw.

Made in the USA.
