You can also make it yourself: it takes 30 Smithing and gives 120 Smithing XP, using Mithril bar. Where the materials come from: Mithril bar (made with 30 Smithing). Making ten takes 10 × Mithril bar and gives 1,200 Smithing XP. Reaching level 30 Smithing takes 13,363 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 30 as ranged gear; compare it with every other piece on the Off-hand weapons list. Off-hand mithril 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 151 less than the shop price, so buying it to alch does not pay.
