I am restoring a GRP boat and bought these blades for cutting GRP and wood. Before purchasing, I tried Bauer (Harbor Freight) BiMetal blades ($8 each) and Bosch BiMetal blades ($15 each). These Twin Town blades last just as long (or should I say just as short) as other brands I've tried, but are a fraction of the price ($1.50 each). Fiberglass wears out blades fairly quickly (again, regardless of brand), so buying 10 blades for $15 makes changing blades after 30-45 minutes of cutting less of a pain.
