The present invention discloses a method for cutting raw or tripe leather with an optimized geometry, which increases the yield of the original raw or tripe leather (A) piece for all the production chain, concomitantly reducing the quantity of solid residues, since the cutting is carried out prior to the tanning stage. Said method is made possible by the use of a cutting table (C) which comprises a top (10) in trapezoid shape, with a plurality of metallic strips (20) juxtaposed in parallel, longitudinally at the lateral ends of the referred top (10). The claimed method has sustainable characteristics and reduces the environmental impact that is inherent to the leather industry, since it enables the use of the generated coproducts, of collagenic constitution, in the food or pharmaceutical industry, reducing the discard of residues in the environment.
