    Well made, but too small

    Posted by Thomas F Baran on Jun 15th 2022

    This knife is extremely well made, its obvious the effort that went into the design as far as construction. But, at least for me, its way too small, and this is one of the largest knives Microtech sells except for the always out of stock Halo and Scarab. As a first responder with extensive active duty military experience, this does not fit what a combat/survival knife should be. There is really nothing to grip on it, so in a fight, or stressful situation where it needs to be used, it would easily slip out of the hand, or having to cut someone out of a trapped seatbelt, this wouldn't be my choice of equipment, its just too small and not practical for survival/combat. I would like to stress again that this is a very well made item, its just not what I would use on the front line.

    Quality knife, lighter than it looks and surprisingly balanced. Would recommend to anyone looking for a functional edc otf blade. Product was processed and shipped very quickly. Would definitely recommend shopping at Eknives.com, very satisfied with my experience.
