Mad Dog ATAK. Early pre-production prototype knife. These are extremely rare and were limited to 100 knives. The common ATAK A series knives currently go for $2895 and 500 were made. This is 5 times rarer, but not 5 times the price. Sheath shows some carry wear and light staining on the nylon. The blade looks like it has wear to the coating from being pulled in and out of the sheath.
