「安物買いの銭失い」の理由：プレミアムなロータリースリッターナイフの経済性を解明
Verdict in 30 seconds: If you’re slitting stainless or high‑strength steels at moderate-to-high speeds—or your downtime costs run above roughly $50,000 per hour—premium Rotary Slitter Knives (HSS/PM‑HSS/Carbide, precision‑ground, coated) win on total cost of ownership.
