I currently have a sharpmaker at home as well as a Spyderco 303M pocket stone with me. I find it hard to sharpen with the pocket stone as Its small. It works gret for a quick sharpen but it just doesn't work to well for a full sharpen. I have not really had any other types of stones or hones, so if somebody could recommend me what I will need for a nice full sized stone. I am used to the ceramic stones, but am willing to try something else. Natural stones also sound pretty cool,
