My first impression is that this is a very substantial and well made steel handle with questionable tool ends. It's a good thing the tool ends are replaceable as the pin end broke off almost immediately in normal (or so it seemed) use attempting to remove the bracelet of a Sinn U1. Both ends of the tool proved ineffective for this purpose. I do not expect I will bother buying a replacement for the broken tool end. I discovered that a different tool with a much lighter-duty handle and an angled pin end was much better suited for extracting the pins and removing this bracelet.
