I've never kept picks this long!
In July 2019, I invented the SVPick. I put a magnet in my pick as I was losing expense Vpicks too regularly. Below is a picture of 2 SVPick's, the one on the left is a Psycho SVPick, made recently, and the one on the right, is a Psycho SVPick I made in July 2019. I know when it was made because it was one of the first SVPick's I made that summer.
This tells me a few things. First, I don't lose picks anymore, second, the magnet is securely epoxied ro the pick, and third, the picks last 3 1/2 years when used every day!
