They do not have any brand name on them but the hook itself is closer to a Boye than a Susan Bates. I would have to guess that they are not a brand I would have heard of before.
They look like the clover brand the older style, if so these are great hooks! If I had the credits Id snatch them up I have two clover hooks they help reduce the stress in my hand and arm I love them and prefer them over all my other hooks :)
