I have a leather skiver made by Severe hdwr sold by Conway Saddle. The previous owner dropped the blade it now has a chip in the cutting edge. I think I need a new blade. It is 10.5" long. The screw slots are 9 9/16 oc and 3/8 wide each. I have not been able to find a blade that wide. It is a great tool. Can any one help me find a blade for it?
