Recommended Knife Guides for those who ask - Bernard Levine's guides some not shown in photo including knife makers of old San Francisco, 4th edition his latest and more are the real deal. I have been reading his guides since I was a kid and checked them out at the local library. Bottom guides in photos are not Levine's but the knives & razors guide to the left cover a lot of Case knives along with razors and some other brands. The one to the right covers Cattaraugus, Queen, Robeson and Russell.. The Levine's guides are packed full of knife knowledge and cover just about everything when it comes to knives plus they are set up in a way that once you learn your way around them they can become a valuable tool for collectors or dealers. I am not associated with any of the people from these guides and this is my own opinion.
