Actually a very decent stamp. I was put off by the product description which made no sense but the item I received is good. The handles are steel and the body is steel or iron. Each piece is attracted to a magnet. The hole is 1 inch and an American made threading die can be easily inserted into it. The set screws have a beveled end. Initially there was little resistance turning the screws in and out, but now they work perfectly. The handles are also removable. buy it again
