The Microtech 231-10 UTX-85 S/E is a compact and highly efficient automatic knife that is part of the celebrated UTX-85 series, standing out for its refined engineering and usability. This model features a single-edge (S/E) blade with a stonewashed finish, which not only gives it a classic, rugged appearance but also serves to mask wear and tear from regular use. The blade is crafted from premium stainless steel, ensuring longevity, excellent edge retention, and resistance to corrosion.

The handle of the 231-10 UTX-85 S/E is contoured and finished in a sleek black, providing an aesthetic that is both tactical and minimalist. The contoured design enhances ergonomics, offering a more natural fit in the hand that improves grip and control during use. This makes the knife more comfortable to handle, especially during extended use or in demanding conditions.

This knife is particularly known for its size-to-performance ratio. It's slightly smaller than the full-size Ultratech but still offers substantial capability, making it perfect for everyday carry. The deployment mechanism is a hallmark of Microtech's design—fast, reliable, and easy to operate with one hand.

Additional features include a pocket clip for secure and discreet carry, and a glass breaker tip which adds to its utility in emergency situations. Overall, the Microtech 231-10 UTX-85 S/E is an exceptional tool for those who value precision and reliability in a compact, easy-to-carry format. It's well-suited for a variety of tasks, from daily cutting chores to more tactical applications.
