BlacksmithDrew Posted September 8, 2013 Share Posted September 8, 2013 So I made a few knives and spears to start learning how to smith. And my newer creations are better. But when I went to the older stuff its more weak and flexible. And will bend but not bounce back into straight shape. Any ideas? Do I have to heat it hotter? Or cool is faster or slower? Thanks for reading. Quote Link to comment Share on other sites More sharing options...
Rich Hale Posted September 8, 2013 Share Posted September 8, 2013 You might,( or might not) want to look into the knife making lessons in the forum. Steve and I have put answers to this and other questions in there with lots of tips...I fo one am not likely to type it all out again,,,, Quote Link to comment Share on other sites More sharing options...
rthibeau Posted September 8, 2013 Share Posted September 8, 2013 you need to learn the heat treating aspects in order to get better results Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted September 8, 2013 Share Posted September 8, 2013 The first question is gonna be WHAT ALLOY? Followed by how did you heat treat it? Otherwise it's like asking "so I need to carry a load; is my truck big enough?" without telling us how big a load or how big a truck you have.

Dodge Posted September 9, 2013 Share Posted September 9, 2013 Care to share details? Maybe some other folks had the same issue on the same metal. :) Quote Link to comment Share on other sites More sharing options...
BlacksmithDrew Posted September 9, 2013 Author Share Posted September 9, 2013 It was an old short sword type creation I made awhile ago, so I just heated up and folded the metal a few times, and re shaped it. It's actually in a real sword shape now. Lol, it was horrible before. But folding it really made it stronger. I also did use clay for the cooling.

Steve Sells Posted September 9, 2013 Share Posted September 9, 2013 what steel did you use that folding made it stronger? and what do you mean by Clay Cooling ? Quote Link to comment Share on other sites More sharing options...
ThomasPowers Posted September 9, 2013 Share Posted September 9, 2013 Folding usually decreases the carbon content---like in the japanese swords where they often start at nearly 2% C and by repeated folding and welding take the carbon content to .5% Quote Link to comment Share on other sites More sharing options...
