Just picked up my first framing slick on Ebay and I've noticed a very slight banana bend on the business end of it. I'd estimate it at about 1/32 - 1/16". I assumed it should be flat like a chisel's back. This is fair amount of metal to remove, if it needs straightening. Should I get a smith to flatten it, grind it, send it back to seller, or keep and use it as is? I haven't had time yet to sharpen it and give it a try...
