These EMT Shears are premium medical grade scissors, manufactured with Japanese steel to ISO standards 9001:2008. We've found 5.5" (14 cms) a very portable size, but also offer a larger version of 7.5" shears, to enable you to cut through 4 ropes with greater ease. Yes you can find cheap shears on eBay for half the price, but trust us... you never want to be in a position where you need to use a safety tool in an emergency only find that minuscule saving prevents you from freeing someone quickly. It has taken us 3 years of searching to find a manufacturer that delivers this kind of quality on this product. As a safety tool, we wanted to ensure we didn't compromise at all. We're sure you're model will appreciate your same level of investment in their safety.
