I bought three of these blades. The first would definitely be a 5 star rating. Smooth cut, straightness, etc. The second blade had a horrible kink at the weld. The deflection is almost 1/4 inch. Basically useless. The third blade was better but still had a slightly curved weld. It cuts and tracks well, but it makes a ticking noise that keeps you on your toes because it's acting like a blade about to snap at a weld. I've been buying Timberwolf blades for years and hope they fix what appears to be a quality control issue.
