I've been looking at metal cutting circular saws and blades. Not a circular saw with an abrasive blade (I've done that before), but circular saws and carbide tipped metal blades intended for cutting upto mild steel.
I looked at the local box stores, I looked at Harbor Freight. I looked on Ebay and at Amazon. There are lots of options. I placed a 9 inch saw and a blade in the shopping cart at Amazon to think about and forgot about it. This morning as my wife was headed out the door she said, "Oh by the way your new saw and spare blade should be here by Sunday."
No, she doesn't have a sister. LOL.
