If you like the Ontario Knives RAT Model 1 but want something a little less bulky, then you'll love the Model 2. The RAT Model II is based on the popular Model I; it's smaller but retains the same great shape and performance as the original. This pocket knife is designed for comfort and performance, with an index finger groove on the handle to keep your hand where it should be and jimping on the spine of the blade for controlled cutting.
