Agree. I tried cutting some stainless with my jeweler's saw and it was so hard the blade just skated over the material. I needed to use my Dremel with a cut-off wheel. My understanding of the rule of thumb for choosing the number of teeth on a blade is to have at least enough to have 2 on the material at all times. Otherwise if the metal is so thin it falls in-between the teeth they will break off. However when there are too many teeth the cut can take forever. Lately I've been using #2 and #3 blades when cutting Nikko blank lugs.
