[Anova]

Leatherworker has two types of tools: A Headknife and an Awl. The Headknife is the primary tool, while the Awl is the secondary. Try to equip the Headknife and not the Awl.

While you can register and create a set for quick switching, to initially access the items, access your armoury system (ctrl+I or through the character menu). Go to your primary weapon slot and you should see a "weathered head knife" or some similarly named tool. Equip and you are good to go. Be aware you may be naked and so will want to buy some crafting armor to help you out. Equip that armor in the same way as before, using the appropriate slot.

BTW, if you have by chance sold the "weathered head knife" (thinking the Lv.5 leatherworker quest gave you the "amateur's awl" as a primary tool upgrade) and cannot use the lv.8 "bronze head knife" (Lv.10 leatherworker quest reward) because your are only Lv.6, you will have to buy a new Lv.1 primary tool from the npc vendor, Admiranda, in the Old Gridania marketplace.
