Mad Dog “A Series” ATAK #A789 with ATAK Sheath. The Mad Dog “A Series” SEAL ATAK’s are some of the most sought after Mad Dog knives around, and for good reason. These knives had all the desired Mad Dog® Knife features like the file worked spine, false edges, laser engraved markings with serial numbers, matching numbered sheaths and beautifully finished black KalGard over hard chrome blades. Some older Mad Dog Knives like this particular one had “Asymmetrical Handles” where the main part of the handle was actually made from a single piece of 3/4″ thick composite that was rabbited in from one side instead of the standard evenly matched 3/8″ thick slabs like on the newer models. The A series ATAK’s started with serial #A500 and ended at #A1000, so 500 total A Series ATAKs were produced, #A789 was the 289th A series ATAK made. This knife is a great example of Mad Dog@ Knives history and fortunately the collector who purchased this one kept in in superb condition.
