I wonder how many of the secondary companies own others that are not listed.
One name missing on the snap-on is sioux tools. I thought I heard at one time that sioux owned the company that is making most of snap on battery powered stuff.
I believe they own sun equipment, Mitchell information and john bean alignment equipment.
I am not sure, but I think Snap-on also owns kershaw knives and I would bet they own all or a part of many other, such as the ones that make their socks, shoes, apparel.
I do know they also have some companies that deal with just their industrial side. Sawblades, bits and taps, plus more.
They also own huge warehouses for nothing but other products. Some I would guess they maybe one of the biggest buyers of many other brands listed.
