Very good quality extra saw (Rarely disappointed Stanley products) Supplied with 2 blades, 1 for metals (the same size as conventional saws can therefore replace) and a wood but with a specific form. The two blades are fixed by a screw on the handle and it fits perfectly without slipping. When storing simply screw the 2 sets (there are 2 notches) not to lose them, and that's it. The product itself is good outfit with a very solid handle, heavy, non-slip. The blades are also of good quality, solid and cut properly. Obviously, this does in no way replace a traditional saw, a saw or screed, because here the more you tend to "cut" only crudely sawn, guidance is non-existent, so it's really in troubleshooting or small saw (pieces of wood, screws screed, etc ...) that we can then tweak. Moreover, the relatively thin metal saw, tends to twist rather quickly due to lack of guidance, a little painful ... At this price, it's still good, can not ask for the moon.
