not craft but use? 1.7.10

[superon]

i'm trying to lock the crafting of an item whilst still allowing a player to use it, in this exact scenario i want players to be able to use a dark matter sword but not to be able to craft one unless a criteria has been completed. i see there are "use" and "craft" options and i've tried those in all the combinations but not managed to achieve this result. false-true and true-true makes it non-craftable or useable, whilst true-false and false-false makes it craftable and useable. i may be missing something simple
