D1-AL Black Hard-Coat 7075-T6 Aluminum Blade

$59.95 $60.90

available as an UPGRADE KIT

This can be used to UPGRADE or replace a D-Series Blade, notably converting a Red Polymer Blade on an Polymer Trainer to have a stronger Blade with an all BLACK appearance.

Alternatively it can be used to convert a Fully Stainless Thrower Edition to have a lightweight Black anodized Blade, noting it is a reduction in strength, but still strong enough for EDC duty carry.

Compatible with:

UPK-D1, D2, and D4
