Manufacture varies and usually has a Utopia Tool's marking on handle
We supply every participant in our antique and vintage sewing machine workshops one of these hammers, making it very necessary to keep our costs as low as possible. It is also important that we can order a large number and be able to receive them quickly without back-orders or delays. Utopia has always come through as our vendor, even when we ordered a hundred at one time.We are, of course, very very satisfied with the price, quality, and prompt shipping and hope to be so for a long time! Thanks!
