The thing that I bought is attached with the hammer part bent a little, and since the scissor bolt did not get in the way, I fixed it and use it by vise and use it. It is convenient because it depends, but uneasiness remains in the strength of each part.
When I had lowered the long hammer, there was a time when I got in the way, but after making it a short double socket electric hammer, it was convenient as it entered the bag. It is good to go 17/13 as well. The fall prevention ring was useful, but as soon as I bought it, I turned the nut a little more strongly, it cracked from inside the grip.
When I was lowering the long hammer to the waist tool, I was paying attention to the finished floor etc, so I was paying attention, but after wearing a short double socket electric hammer hammer, I did not need to worry. I have only 17 sockets outside my body, but 13 is good too. A slight difficulty is that the fall prevention ring catches on the hammer holder.
