Ok. So, I own 4 Red imps all Case 132's..1 is an NOS 6/8, 1 is an NOS 9/16, 1 is a used 5/8, and the other a 6/8 that was honed down to 5/8 to straighten the edge .I also owned an NOS Morris 133 5/8 hat I sold, because I like the wedges..Anyhow, out of 5 imps that I have or have had, one of them, the original 5/8 Case 132, is Magnetic......So apparently the steel on the Case Imps is not all the same......Is there any benefit or liability to Magnetic Steel?
