Look at the stickied post for
SKILL GAIN GUIDES above. That's what it is there for.
Shurikens (weapon) and circlets (a type of headgear) are your best bets, in terms of skill to make combined with ingot use. Remember to have GM mining, plus gloves of mining to goo over 101.1, and use the salvage bag from the provisioner, to get the maximum return from recycling the crafted items to get your ingots back.
Instructions on using the bag are in several stickied posts.
