Ok I have a custom order that came in and it is very new to me. The customer is wanting a Damascus san mai blade 3/8 thick and about 2.5 in wide. Ok I have made the Damascus out of 5160, 15n20 and 52100. I am looking for a core that will give good contrast. I would love a stainless core but don't have the tools to make it (unless someone would volunteer to weld it up for me). Can anyone recommend a good core for me ,also what thicknesses I need to achieve the 3/8 thickness. I have made the Damascus to the 3" wide and 3/16 thick and have ground it smooth and would like the core to show up to about a 1/4 to 1/3 of the blade. Any good suggestions would be appreciated.
