Purchased Teflon/Tefzel Wire Stripper Blade

My Ideal StripMaster wire strippers came with the L-4421 knife blade.  This is fine for typical PVC insulation that most things are wired with, but it isn’t ideal for the tefzel insulated wire used in aircraft; the sharp edge can nick the wire.

The correct blades for teflon/tefzel are L-5211, but these are expensive (~$100).  I lucked out and found a set on eBay for $10 though so I picked them up.
