Constructed from high-carbon tool steel for strength and wear resistance, the bar is a solid one-piece, milled from high-carbon steel for consistent performance. Rails are precision-ground to uniform tolerance to ensure even chain engagement. Sprocket tips employ large-diameter sprockets encased in heat-treated carbon steel to improve durability, and the extended tip design lessens chain "hammering" on the bar rails to prolong service life. The TsuMura Pro "FV" tip is specifically engineered for long life, featuring a thick sprocket and robust cogs for reliable operation.
