/diy/ - Do It Yourself

i need your help /bmg/
my brother got into drugs bad, went to jail for a while, went through that cycle a few times
but he's been out since february, and he's really gotten into blade making. i figure he picked it up in jail. he's gotten a few tools for it, and recently assembled a little furnace in the garage
i want to encourage him in this hobby. anything's better than being bored and turning back to drugs
so what can i get him for christmas that a blade maker would want
