Ron,

If I remember correctly, I picked them up years ago at our local electrical / plumbing wholesale distributor.
This would not be a " electronics " store.
Any distributor that sell wholesale to electrical contractors should have them or a similar high quality.
The strippers that G.R. posted a link to look impressive also. I think I might even try to locate a set of them here.
I will try in the meantime to locate a part # for the ones I have.
