Since its release back in 1999, the Microtech Ultratech has stood as one of the most well‑known flagship OTF out‑the‑front automatic knives on the market. Widely adopted by overseas military‑tactical users as well as knife collectors, the Ultratech built a solid reputation as a benchmark tactical auto‑knife over more than two decades.
Even so, early‑generation Gen1 and Gen2 Ultratech models carried a widely‑discussed structural shortcoming common to traditional OTF designs. Once the blade fires out into position, there is noticeable blade‑play, meaning the tip will show slight side‑to‑side wobble. This flaw existed even on genuine factory‑original units. For most users, near‑zero tip stability could only be achieved with expensive custom hand‑built knives. That is where the updated Microtech Ultratech EX‑ZBP, short‑named UTEX, enters the picture.
Key Dimensions & Build Specs
We list all key physical parameters for the UTEX so collectors and tactical enthusiasts can quickly evaluate its size and weight for carry purposes:
- Overall length: 21.1 cm
- Blade length: 8.2 cm
- Blade width: 1.6 cm
- Blade thickness: 3 mm
- Blade steel: D2
- Handle material: Aluminum alloy
- Handle length: 12.5 cm
- Net weight: 98 g
- Package dimension: 16.5 * 8 * 3.5 cm
- Package weight: 155 G
Weighing only 98 grams with an aluminum handle, this OTF keeps a lightweight profile without sacrificing structural rigidity. D2 steel brings reliable edge retention, making it suitable both for collection display and real‑world tactical‑utility cutting tasks.
What Makes EX‑ZBP (UTEX) Stand Out
The biggest improvement of the UTEX focuses on solving that age‑old OTF blade‑play headache. Many fans of the Ultratech series accept minor tip wobble as an unavoidable feature of older‑generation OTF mechanics. This iteration reworks internal structure to reduce tip movement, removing the need to step up to high‑priced custom‑made knives for stable tip performance.
For collectors chasing the classic Ultratech silhouette but frustrated by the wobble on Gen1 and Gen2 versions, the EX‑ZBP delivers much‑wanted improvement. It preserves the familiar look and feel of the iconic Ultratech platform while fixing one of its most criticized drawbacks.
Closing Thoughts
Decades after the original Ultratech changed the OTF‑knife space, the EX‑ZBP (UTEX) brings meaningful mechanical upgrades to this legendary platform. It appeals to tactical end‑users as well as serious knife collectors who value both form and mechanical precision.
