Microtech 135-1BL LUDT AUTO 3.375" Black Plain Blade, Blue Aluminum Handles


MT1351BL: 135-1BL LUDT, Blue Standard


The LUDT is the large version of the Underwater Demolition Team knife. It led its way into the knife market in the mid-1990s and quickly became one of the fastest selling knives in Microtech's history. Over the years, the LUDT has been shaped and changed to fit in the ever-changing market. The LUDT was discontinued from Microtech's lineup for a period of time so we're pleased to see this guy make its way to us.

The 135-1BL LUDT's blade has a crowned spine, thumb ramp jimping and a reinforced tip for maximum penetration effectiveness without compromising the tip. The black finish on the blade and purple on the handle are extremely durable and makes this an ideal folder for tactical operations. All the hardware of this knife including the actuation button and pocket clip is matte black to create a nice contrast. The handle is made from milled aircraft grade aluminum for strength and to keep the weight down. It's ergonomic, lightning fast and just an awesome all around blade. This knife has been proven time and again, and we are very happy to have it back again. It includes a micro cord lanyard and tamper-proof screws.

    This knife surpassed my expectations. Sturdy. Flips out super fast. Don’t hesitate to buy one. Especially from OTB Firearms. Their customer service was great when I had a question. I really need a Socom from Microtech. Waiting for one to come in stock.

    Quality built and functions perfectly. Solid lockup and great ergonomics. My grip on the handle is rock solid because of the design. Terrific customer service from "Only The Best". Fast and secure shipping. Excellent and multiple notifications throughout the purchase process. Fair and competitive price.
