In the strider_egg recipe, this mod used the tag "forge:tools/pickaxes" instead of "minecraft:tools/pickaxes"
Many mods' mining tools do not come with the forge pickaxe tag, resulting in many cases where only the vanilla pickaxe can crack strider eggs
it should also use the vanilla pickaxe tag since more and more mod pickaxes do not contain forge pickaxe tag.

change the tag into minecraft:tools/pickaxes could solve the problem

I was checking the recipe datapack of farmers' delight and I realized that FD is using another recipe datapack

I'm not sure if using pickaxe was a deliberate design. If yes that would not be good idea because some tools such as Electric drill, chisel also could do these job, but they do not contain the pickaxe tag
