Personal security with a discrete, cosmetic appearance hides the 3.25 inch blade. The blade is hardened stainless steel with a black finish. Double edges on each side are sharpened and a nice point serve well for cutting and piercing. A stiffened ridge runs down the blade for additional blade strength. Sheathing of the blade is secure and has a tight hold. While the exterior appearance is that of a normal masculine comb, it houses a force to be reckoned with.
