The Ontario RAT model 1.5 is a mid-sized version of one of the most popular, well-loved pocket knives of all time. The Ontario RAT models 1 and 2 are lauded as excellent working knives, and the model 1.5 doubles down on that by using CPM MagnaCut steel for the blade. This steel has great edge retention and fantastic corrosion resistance and toughness, ensuring it will survive any cutting job. Size-wise, it's just larger than the model 2, nailing that Goldilocks sweet spot. It may just be the best version of the Ontario RAT yet. If you need a time-proven tool you can count on, this knife fits the bill.
