The YOUNG MACHINE #1212, #1624 Rotor Knife is a precision-ground rotor knife manufactured to OEM tolerance at our New England facility. We supply, sharpen, and fabricate industrial blades across plastics processing, packaging, paper, food processing, slitting, and metalworking applications.

Specifications. Model Numbers: #1212, #1624. Material substitutions (M2, D2, A11, powder metal, tungsten carbide inlay) available on request — we’ll recommend the right steel based on your run hours and material hardness.

We’ve supplied and serviced this fitment for years. Send your model number and any photos of the existing blade; we’ll cross-reference, confirm OEM tolerance, and quote in 24 hours.

Already have this blade? We’ll regrind it. Most operations save 40–60% by regrinding before replacing. Send us your existing set; we’ll quote a regrind in 24 hours and tell you honestly whether it’s still worth saving.
