Beastflensers' tools
Beastflensers' Tools (10gp) allow a proficient character to carefully and correctly extract the valuable parts of most every slain creature – meat, hide, bones, flame-bladders, and more - so long as the flenser is aware the part of value exists or identifies it during the butchery. Butchering with other skills: Survival, nature, and cooks’ or leatherworkers’ (hide only) tools may also be used as substitutes, though do so with disadvantage.undefinedNote that this disadvantage is easily countered by the advantage for creature familiarity (see above).
 * The DC harvest to harvest a creature generally depends on it's CR, it’s size, and it's creature type.
 * The GP values of a creatures’ parts (successfully harvested) also tends to depend on the above.
 * If the DM decides that you are closely familiar with a creature, they may grant advantage on your check.
 * For every size category above medium, the time to butcher is doubled and the DC is raised by 3.
 * For each size below medium, the time is halved and the DC reduced by 3.

Not of flesh: Certain creatures' remains cannot be harvested with beastflensers’ tools. Depending on the creature, however, the following might (DM discretion) be usable:
 * Constructs: tinkerers', blacksmiths', masons' or miners' tools
 * Elementals: alchemists' Tools
 * Oozes: alchemists' Tools
