1 1/4 inch oval skew with the curved cutting edge. I have a 1 inch skew with a curved edge. Once the blank is round I move down to a 1 inch skew then smaller as the blank gets closer to final size. I have two round skews I really like...round as in made from a round bar stock. These two have straight cutting edges. I have two others that are have convex bevels instead of straight or hollow ground. I really like these also. I just like using skews. Skews rock! round, oval, flat, curved, hollowground, convex or straight bevels.....
Taking time to learn to use the skew was a lot more fun than spending the same amount of time sanding. My sanding starts at 320.
Do a good turn daily!
