Alright so I'm fairly new to the sharpening scene and I need some help. All I have for sharpening equipment is the Spyderco Sharpmaker, and I've been sharpening my knives following Sal's steps. Now I have stumbled upon terms on these forums such as burrs and stropping. I've interpreted burrs as the metal you're sharpening sliding over to the other side of the knife that is not being sharpened at the moment, is this correct? As far as stropping goes would somebody please care to tell me what this is, and if I need to worry about it? If I have the right understanding of burrs, should I be following Sal's steps, alternating 25 strokes for each side of the knife, or should I only sharpen one side until I notice a burr, then switch till I notice another burr? I'm going to stop before I confuse myself....please help.
