Hey all, I've been working a large Camp Knife made from a leaf spring and used the forge to straighten it out and do a bit of shaping. I was sanding off the grunge on the belt sander when I noticed there is a crack in the top quarter of the blade that goes about half the thickness of the steel and travels maybe a quarter to a half inch down from the back towards the edge. Now this is a fairly huge piece of steel that was going to serve as a wood chopping, bottle opening, all around heavy use camping blade. What I want to know is if the experienced forging folk out there can tell me if this kind of thing can be repaired? Should I hack the stock short at the crack and start over? Should I just re-adjust the demensions of the blade to grind out the crack? for the record, the steel appears to have some chromium in it so I'm guessing 5160. This is the second time I have run into this problem with what I think is similar material (based on appearence and behavior). Is it possible to heat it up and repair the crack? On the last piece of metal I tried folding the cold metal over in the vise at the crack to see if it would break and it didn't, so I'm guessing this kind of thing is localized. What is the opinion of the experts out there? It's all new to me.
