This is the script I am using but it places the flint knife in the grid instead of using it as the tool

recipetype:stone_age:flint_workbench.addRecipe("fiber", item:survivalist:plant_fibres *4, [[item:minecraft:dirt, item:minecraft:dirt]], item:stone_age:flint_knife);

the <> symbols are around the items but github doesn't show them

FYI I am able to get recipes to work without a tool like this:

recipetype:stone_age:flint_workbench.addRecipe("fiber", item:survivalist:plant_fibres *4, [[item:minecraft:dirt, item:minecraft:dirt]], item:minecraft:air);

Seems 1.16.4 is broken too. As mentioned above simply changing needed tool to an item like flint helped for now.

Can you describe your problem, because its working as expected!

• craft 4 stones using 2 dirts and activating by flint knife:

import mods.stone_age.FlintWorkbenchManager;

<recipetype:stone_age:flint_workbench>.addRecipe("test", <item:minecraft:stone> *4, [[<item:minecraft:dirt>, <item:minecraft:dirt>]], <item:stone_age:flint_knife>);

• craft 4 stones using 2 dirts and activating by empty hand:

import mods.stone_age.FlintWorkbenchManager;

<recipetype:stone_age:flint_workbench>.addRecipe("test", <item:minecraft:stone> *4, [[<item:minecraft:dirt>, <item:minecraft:dirt>]], <item:sminecraft:air>);

Don't forget that it is shaped recipe.

Still its working like a charm >>>

recipe:

<recipetype:stone_age:flint_workbench>.addRecipe("nameless_tetra_workbench", <item:minecraft:crafting_table>, [[<item:minecraft:dirt>,<item:minecraft:dirt>],[<item:minecraft:dirt>,<item:minecraft:dirt>]], <item:stone_age:flint_knife>);

- setup
- after right-click

fyi try to use latest mod version 1.2.5

Got it: there is problem when durability does not match.

I am not sure if it is a durability issue. I also tried it with a full flint tool. Let me test it quick with the latest version.
Also, my pack is quite large at this point. So a cross mod conflict could also be a possibility at this point.

I tried it with 1.2.5 and for now the durability does not matter. So a full ore used flint tool makes no difference.

Strange, because for me it makes difference

<recipetype:stone_age:flint_workbench>.addRecipe("nameless_tetra_workbench", <item:tetra:basic_workbench>, [[planks,planks],[planks,planks]], <item:stone_age:flint_knife>);

Its possible that CraftTweaker has something to do with it. Anyway I recommend to update my mod after I release next v1.2.6

I am not sure to be honest. Also JEITweaker does not work perfectly as it does not add JEI descriptions anymore. My major problem is that there is no time to figure out which of the 140 mods breaks stuff at the moment. If its working within a base setup of CraftTweaker + Stone Age, then something else seems to break it.
