In my kid show I do a fork bending routine, and these are the best forks (in my opinion) for fork bending!
You get three dozen of them for $10.99 at Costco. Not every Costco sells them, you need to find a Business Costco. You don’t need a business membership to go to one; these locations just cater more to restaurants than a normal Costco. I’m sure you can get them online as well.

PS: An early version of my fork bending routine is in Vanish Magazine and I’m writing up my current routine for an upcoming book and lecture called: Two Openers, Two Middles and Two Closers for Kid Shows.
