I bought a box of DE Reavers for some of the bits, but the majority of the kit is left over, and there are enough extras in the kits to replace some of what I used.
If you bought two kits, you will have enough extra bits to make 3 complete reavers (I just used 3 hoods and blade sets, and each kit comes with 4 sets) I would be willing to trade the leftovers for something or sell them cheaply if anyone is interested.
