I've owned both. I think that the Ontario Rat knives are good knives. They were designed by the guys who now own and operate RAT Cutlery. Where RAT Cutlery is so much better is in the quality control, more consistant and better heat treat of the blade, better attention to detail, the no questions asked warranty, and their customer service. You're not going to find the owners of Ontario Knife Co. on a forum like this participating with us regular dummies. The RAT Cutlery guys make themselves available to the customers all the time. In fact, a lot of us have their cell phone numbers because they post them here every once in a while to make sure that people can get in contact with them without having to go through any hullibaloo. RAT Cutlery also believes more in having a community to learn from and the training aspect of being a knife and outdoors enthusiast. They're not just making knives to try to get the most customers and the most money possible. They do cost a little bit more, but you get a lot more for your money than just a good knife.
