Microtech has updated the venerable Ultratech knife for 2015. While the dimensions and action remain the same as the previous model, this latest version features the effective, visually stimulating "tri-grip" texture. Further enhancements include beveled edges, a modified thumb slide, tri-angle hardware, and an everyday-friendly glass breaker tip. The end result is an impressive Ultratech that improves upon what has become the must-have OTF automatic.

This Ultratech has a satin finished bayonet style blade with a plain edge and sharpened upper cutting edge. Its blue anodized 6061-T6 aluminum handle has black finished pocket clip, glass breaker and stainless steel hardware.

For those unfamiliar with the Ultratech, it's a fully automatic knife with a double-action out-the-front mechanism, meaning the thumb slide deploys the blade and retracts it as well. The Ultratech knife from Microtech has set the bar for all OTF knives.

This is the absolute best OTF I've found. The size is functional for most daily tasks while the weight is so insignificant you must remind yourself where you've stowed it. The blade is as sharp as any knife I've got to include my Kershaw's. The action is purposeful both deploying and retracting. The blade is very tight both deployed and retracted showing infinitesimal wobble and no rattle whatsoever. This is a definite keeper and I believe is the best value I've found. Strongly recommend!
