The Microtech Ultratech is the first ever OTF (out the front) automatic knife produced by Microtech Knives. The D/A dual action automatic that started it all is the smoothest operating out the front you will find. It features a 3.4" blade. The Ultratech has a 5" anodized 6061-T6 aluminum handle with bead blast finished pocket clip, glass breaker and stainless steel hardware. The double action slide switch allows for fast automatic deployment and retraction when you need it. The slim design of the Ultra make it the perfect EDC knife.

    Great OTF knife, would buy again.

    Great knife, great steel, great smooth action. I love it. The one complaint I have, is the pocket clip sucks. It is not tight to the handle at all, it will slide right off your pant. It does not hold well with the clip, I hate it actually. But, I love the knife so much I carry it differently lol. So take it how you will. I would buy again and plan on it. I will just be looking for a better clip alternative to switch to.

    Great experience.

    I wanted another ultra tech as an everyday, so this one will be a worker. No need to review the knife - it’s a Microtech. This was my first time buying with EK, though. Clean and easy online process, great updates on order progress, and delivery was very timely. Exactly what you’d expect from larger dealers or mega knife vendors. What I didn’t expect were the personal touches in the emails, the hand written note in my package, and the goodies let me know there was someone on the other end of my purchase. Very nice and I’ll be buying from EK every chance I get.

    Microteck automatic blade front.

    It is a great product. The transaction was quick. They always answer and are accurate. The blade of the steel is M390 which is rated 9 by counting from 0 to 10. It is an excellent material. Cut like a razor for parba. The knife is very safe because to open and close I don't have to touch the blade so I can't cut myself. I recommend it and buy it again. What a little. But quality costs and stays with you. you notice the quality when you use it.

    Sweet Service and Great...

    Been scoping out a knife like this for a while. Really pleased with this knife. It’s extremely well built and extremely sharp. I had some back and forth via text and quite pleased with that service. They are fairly quick to respond. I don’t believe they have anyone manning phones but that was ok with me. Definitely will buy from them again.
