Strippng wire

Hope this is not a repeat, but I don't remember anyone using this way of stripping wire. I know it won't work on new wire but old wire works good for me. I have an old railroad iron as an anvil ( use what you want) and I lay the wire on the anvil and tap it with a hammer. The insulation then comes off by hand and at todays prices in my area turns $1 a lb. wire into $2.50 a lb. wire. Could be nonsense, but may help out someone sometime.
Happy Scrapping....
