Can't find the thread but it was this tool Power8Workshop
Great design but I don't think the build quality is there, plus it looks as though it is trying too hard to rip off the Festool brand
but more importantly I had a look at what other tools they do and on the first page of their UK website they have a multitool like the fein and Bosch, the replacement blades are very cheap. I have the newer style Fein and I don't think mine would take these blades but from how people describe the old fein and the Bosch I think the blades would fit. Might be useful to the bosch users?
