This once over common item has become exceedingly hard to find.
This is a Fender extra heavy pick.
This is the very last one I have. I hardly ever, to my dismay, use it.
I've been trying to source some.
The problem is, so are a lot of other people.
Angus Young pays hard cash for them.
His tech keeps them in a lock box.
They are literally more valuable than gold.
When I was a kid I bought them 10 for $1.
As a teenager, 4 for $1.
If You spent a substantial amount in a shop, a complimentary bag of 25 or so was handed over. As a Young adult they were scattered all over the bottom of an accessory case that was actually a hardshell Samsonite women's overnight grooming and dressing carrier. It was originally my Grandmother's flight carry on.
For some time I also used Tortex extra heavy and heavy. The strike seemed less harsh. But eventually I realized nothing matched the Fender extra heavy.
For some strange reason, Fender discontinued them.
That's why they are so rare and valuable.
