It features a 3.4" blade with various blade finishes and styles. The Ultratech features a 5" anodized 6061-T6 aluminum smooth handle with pocket clip, glass breaker and stainless steel hardware. Dual action thumb slide for automatic deployment and retraction.

    Great knife. Fantastic actually. Nothing comes close to the craftsmanship that goes into these knives! Just so pristine! Enuff said. The word Microtech says enuff.

    1st off let me say that eknives is such an amazing company to deal with. Super friendly/helpful employees. Super, super fast shipping and outstanding prices. Now the knife. This is my 2nd microtech ultratech and this one by far is my favorite. Like the other one Microtech sends thier knives out scary sharp. The fit and finish is absolutely top tier. If you're on the fence about one of these or really any Microtech i say GO FOR IT! You will not be disappointed. Just make sure you get it from eknives!

    Microtech is the best knife in my opinion. I have a large collection and the ultratechs are my favorite. Super easy to cary and so reliable. Had been looking for a red one for a while. Stumbled across EKnives. Purchased from them and was so impressed with the level of customer service I received. Had a question before and a purchase and both times they answered the phone and my questions. Perfect product/perfect transaction
