The WORTEX 2038HD UP757, UP957 upstroke Knife is a precision-ground blade engineered as a drop-in OEM-spec replacement for TRIA equipment. Manufactured to original-equipment tolerance and ground at our New England facility.

Specifications. Send us your part number, dimensions, or a photo of the existing blade — we’ll cross-reference from a catalog of hundreds of fitments and confirm OEM tolerance before quoting. Material substitutions (M2, D2, A11, powder metal, tungsten carbide inlay) available on request.

TRIA’s Italian build tolerances differ enough from US/German granulators that a generic-spec blade will under-perform. We grind to TRIA spec — including 30° and 45° bevel variants — and we’ll cut a custom bevel if your application calls for it.

Already have this blade? We’ll regrind it. Most plants save 40–60% by regrinding existing blades instead of buying new — and most OEM steels still have life left long after operators assume they don’t. Send us your worn set and we’ll tell you honestly whether a regrind cycle still works.

Same-day pickup across New England — MA, NH, CT, RI, VT, ME. Custom dimensions, non-standard materials, and one-off retrofits welcome. Call 508-987-6800 or request a quote online. 25+ years of industrial blade service to OEMs, recyclers, packagers, paper mills, and food processors.
