From Mabinogi World Wiki
- It would be better to use one of the gathering tools (i.e., the Gathering Knife or Sickle) instead of a sword to make leather straps. A sword would get a poor return in the proficiency it gains for the durability it loses, as compared to use in combat. The gathering tools would be cheaper to repair and to buy more, should their total durability become zero.
- Leather straps are used as materials in blacksmithing, tailoring and handicraft.
