Second tool crafting recipe

hi, i got the recipe to make the tool crafting part from the npc in stronghold but when I made it, it has a stronghold symbol on it and I can not use it to craft my tool. ii read that there is another recipe for normal ingredients but that npc only sells one recipe. Where is the other one located?

The recipes are sold in your stronghold, in the group of 3 ncps standind in a triangle close to your changing merchant. Its the most right of the 3.

thanks i found it
