Rey,
welcome to the forums. i am a newbie myself but here is the deal. it takes a certain amount of carbon in a steel to make a knife. the stuff at lowes and home depot is just mild steel meaning it just wont work.
some of the more popular blade steels as far as carbon are these.
O1, W1, D2, W2, A2, 1080, 1084, 1086, 1095, and 5160. now this isnt everything i am sure others can and will add to it. and i wont even go into any of the stainless steels cause i just dont have a clue to be honest.
here are some websites that you might find helpfull.
admiralsteel.com
fastenal.com
flatground.com
onlinemetalsupply.com
southerntoolsteel.com
texasknife.com
mcmaster.com
midwestknifemakers.com
this list is not everyone but it will get you going.
there are also a couple guys on here and around that sell good steel and have great reputations you need to email them both and they will send you a list of what they have.
kelly cupples at
octihunter@charter.net
and Aldo Bruno at
njsteelbaron@gmail.com
also there is a newbie sticky at the top of the forum with some good info in it. some of it needs to be redone.
could some one post the google search for knives for him?
good luck Rey
