Mr. Emerson in your opinion is it better to choose a folder with a hole in the blade to open it or a pin or stub (I apologize if I'm not using the correct terminology). It would seem to me that if your hands are dirty or sweaty that the stub might be more foolproof. Also, is it possible for you to give a brief summary of the steel descriptions and which is better? I see so many ways that knife steel is described I get very confused. Is there some rating below which we should not go in purchasing a knife? Thanks in advance.
