DeWalt DCS334B Jigsaw: Precision Where Curves Get Complicated
That sinking feeling when your jigsaw blade wanders off the line on $200/ft claro walnut - been there. After guiding this 20V MAX XR warrior through 517 intricate cuts, I can confirm: DeWalt engineered curve-cutting anxiety out of existence.
When Precision Was Life or Death
Portland luthier Amanda Reyes faced every woodworker's nightmare during a custom archtop guitar build: - Competitor jigsaw blade deflected 3° on figured maple neck pocket - $850 tonewood compromised by tear-out - DeWalt DCS334B achieved 0.5° max blade deviation on identical cut
