Crystal knife
Crystal knife is a members main-hand weapon. No shop sells Crystal knife and no monster drops it, so an Ironman makes it: it takes 80 Smithing and gives 300 Smithing XP, using Crystal tool seed and 150 × Harmonic dust. There is one other recipe below.

Ironman verdict
Where the materials come from: Crystal tool seed (dropped by Edimmu (level 122)); Harmonic dust (sold by Travelling Merchant's Shop for 2,000,000 coins). Making ten takes 10 × Crystal tool seed and 1,500 × Harmonic dust and gives 3,000 Smithing XP. Reaching level 80 Smithing takes 1,986,068 XP in total; the Smithing calculator counts the actions and materials to any target, and the Smithing guide has the Ironman training route. It is worn in the main-hand weapon slot; compare it with every other piece on the Main-hand weapons list. Crystal knife is members-only. It is untradeable, so every account, Ironman or not, gets it the same way.
