Start out with flea market knives from the dollar box. I like to stand while sharpening long knives so I can rotate my torso at the waist. The shorter knives I do sitting, using arm motion only. Flip your stones end for end from time to time to even up the wear.
If you don’t feel like rotating your vise 180 degrees, just walk around the table.
