This is the finer of the two blades available for the Wild West Joinery Saw. It starts cutting at 18 TPI, goes down to 14 TPI and then back up to 18 TPI. The blade is .020" thick plus .005" total set, for a working thickness of .025". This is a relatively stiff blade that works well in thinner hardwoods. All of our blades may be returned to us for sharpening ($15 sharpening fee), and they are available in rip and crosscut configurations.
