I'd probably use 1095, and draw it to a spring temper (blue) after
hardening. I wouldn't buy anything fancier than 1095, unless for cosmetic
reasons (ie stain resistance or something).

Hi All;

I need to make a special 'box end' wrench for a particular job I do
frequently. It's not complicated, overall dimensions would be about 1.25"
X 6" X 1/4". One end would have the special shape machined in, and the
other end would have a 3/8" square hole for a 3/8" ratchet. Regular mild
steel deforms with regular use, so I lose the good fit on the fastener
after I've used it a couple of times. I want to use some tougher stuff,
but I'm not sure what would be best. 4130 hardened and tempered after
machining?
