I have the pwc9 blue point strippers that are stamped usa. They worked fine back when I used them. I use the matco branded cheap looking plastic auto strippers. Those work great. Haven't touched the blue points since, except to check for the usa stamp after reading this
Yeah I never use a tool like that.
When I'm wiring...home or auto...
Strippers like these are amazingly wonderful.
The only time they're not good is in super tight areas.
