Backed by 10 years of research and tested in the field by paramedics, emergency physicians, Navy SEALs and a NASA flight surgeon, the 8-in-1 HÉROS shears are truly built for battle. They’ll cut through virtually anything: carbon fiber, kevlar, leather, seatbelts, heavy plastic, your boots, luggage, you name it. Made of Japanese AUS-8 Steel, they cut with the power of a Great White’s jaw yet stay sharp no matter what you put them through.
