Two-fisted protection meets ultimate comfort with features for customizable fit

The sporty styling and tasteful green accents capture attention, but it’s the multi-pronged approach to protection that keeps workers coming back to Brass Knuckle® Spike™ (BKADJ-5060AFP) again and again. It protects eyes and vision on two fronts with BK-Anti-Fog+ and UV 6 protection, then adds a host of customizable comfort features for the ultimate fit.

BK-Anti-Fog+ isn’t a coating at all—it’s a technology. The anti-fog layer is molecularly fused into the lens during manufacturing, forming a permanent bond that resists breakdown from heat, humidity, or repeated cleaning. By contrast, most anti-fog “coatings” are low-cost topical applications that can wear off, scratch easily, or degrade with exposure to chemicals and abrasion. BK-Anti-Fog+ delivers reliable, long-lasting fog resistance that maintains optical clarity through the harshest conditions. It outperforms conventional coatings by orders of magnitude, exceeding the world’s toughest anti-fog standard, EN 166/168, by a factor of 45.

Next, UV 6 protection blocks 99.99% of UV radiation, shielding against both UVA and UVB rays to help prevent eye damage from prolonged sun exposure or intense artificial UV light found in welding and other industrial environments.

Finally, a wealth of design refinements creates an easily customizable fit for virtually any face. The standout feature is a five-step, angle-adjustable temple—ratcheting up or down through five click-stops for a truly personal fit. A floating, reinforced-rubber nosepiece conforms to the bridge of the nose, an integrated soft brow guard adds comfort, and flexible rubber temple tips ensure all-day wearability.

And let’s face it—the rimless lenses just look cool. With Spike, workers never have to sacrifice style to get the ultimate in comfort and protection.
