This is the coarser of the two blades available for the Wild West Joinery Saw. It starts cutting at 16 TPI, goes down to 12 TPI for 2 inches and then back up to 16 TPI. The blade is .025" thick plus .005" total set, for a working thickness of .030". This is a stiff, relatively coarse blade that works well in thicker hardwoods. All of our blades may be returned to us for sharpening ($15 sharpening fee), and they are available in rip and crosscut configurations.
