They are made from a big bandsaw blade that is L-6 steel 1/8th inch. I have a ton of the steel. I really like working with it! Thanks for looking! I will be out to your fine state on tuesday to try to get a gobbler or two then over to kansas for the same. A friend of mine lives in smithville just north of kansas city! We are filming the hunts for a tv show that he works for! I hope we have great weather!
