Back Door Entry. Still Dangerous.

Why the Ultratech Still Leads

The Ultratech remains the benchmark for American-made OTF knives. The Gen IV platform refines ergonomics and internal geometry while maintaining the durability Microtech is known for.

The double edge blade provides symmetrical performance with a clean, aggressive profile, while the stonewash finish helps hide wear from use.

Blue anodized handles give this one a sharp, confident look without being over the top.

Why Used Still Matters

We don’t always get to choose products made in the USA. Most categories simply don’t offer that option anymore. Pocket knives are different. There is still a strong American manufacturing base building tools like this right here at home.

Whether new or used, supporting American knife makers helps ensure that continues.

If you’ve been looking for a clean Ultratech at a more accessible entry point, this is a strong one.
