As soon as you pick up the Microtech Dirac Delta 227‑10, its compact yet robust construction, smooth automatic action, and versatile design immediately stand out, making it suitable for both everyday carry (EDC) and more demanding tasks. The Dirac Delta represents a modern interpretation of the popular Dirac line, combining portability, precision workmanship, and high performance.

Made and assembled in the USA.

🗡️ Blade – Stonewashed

The blade on the Dirac Delta 227‑10 is single-edged, automatic, and features a stonewashed finish. This matte, lightly textured finish not only reduces glare, but also effectively conceals minor scuffs and scratches from use.

Advantages of the stonewashed finish:

discreet appearance suitable for everyday carry

effective masking of wear

stable and versatile cutting performance

A modern, high-quality stainless steel is used for the blade. This steel provides:

good edge retention

corrosion resistance

solid performance in regular use

easier maintenance

Features:

strong and lightweight construction material

comfortable ergonomics for everyday use

resistance to moisture and wear

minimalist tactical appearance

The reversible pocket clip allows carry on either the left or right side.
