Sterling 921 heavy duty utility blades: the standard trapezoid blade for trimming knives. Snap-off segments or fixed edge depending on your knife style; fits most common trimmers.
Keep a sleeve in every toolbox and the tube bucket. A blunt blade tears tape, drags backing rod, and slips; a fresh one costs cents.
Fits most standard trimming knife styles.
Heavy duty steel holds an edge through packaging, rod, and tape.
Sold per sleeve so fresh edges stay cheap.
Fit per the knife's blade-change instructions. Extend a fresh segment or swap the blade when cuts start tearing instead of slicing. Snap worn segments with pliers, never fingers.
Sharp edges: store sleeved. Dispose of used segments in a rigid container, not loose in the bin.
