Ironman verdict

2 monsters drop it. The easiest is Brutal green dragon (level 105, 1.5/128); the best rate is Ferocious barbarian spirit (level 106), at 2/128, about one every 3 kills. You can also make it yourself: it takes 40 Smithing and gives 170 Smithing XP, using Adamant bar. Making ten takes 10 × Adamant bar and gives 1,700 Smithing XP. Reaching level 40 Smithing takes 37,224 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 off-hand weapon slot at tier 40 as ranged gear; compare it with every other piece on the Off-hand weapons list. Off-hand adamant knife is available on free-to-play worlds too. It is tradeable on normal accounts, but an Ironman cannot use the Grand Exchange or trade for it, so the sources on this page are the whole list. High Alchemy turns one into 9 coins, which is 141 less than the shop price, so buying it to alch does not pay.
