Hello - We recently acquired a large Japanese box containing vintage tools some of which we believe may be for leather working. We would be most grateful for any comments about their use. We in particular are unsure what the brass "pricking tool " is used for ( if it is such,) as it is seems too thin to be a punch. The box also contained 2 metal frames which we wondered whether they may be for stretching pelts/hides ? We grouped togther all the other tools that we couldn't identify and wonder whether these too have leather working associations. By way of background we believe that the contents of the box are 50 years plus and the other tools included in the box were saws , planes and metal blacksmith items such as a vice and varius tin snips. My wife and I are retired and enjoy doing up old tools as a hobby and returning them to circulation. Any help woud be greatly appreciated. Bob and Bryony
