youtube’rejects videos over 10 mins. unless you’re enrolled in their Ad program. I will not sell out to the program, so this video is part 2 of the knife review! Review of the Microtech UTX-70, UTX-85, Daytona, LUDT and the Piranha Miniguard automatic knives. The Microtech UTX70, Microtech UTX85 and Microtech Daytona are dual action out-the-front, or OTF, knives. The Microtech LUDT and the Pirahna Miniguard are side-opening automatic knives. There is little info about Piranha Knives, so if you have any info about this company or their offerings, please let me know!
