I bought these items for crafting so I can't comment on how well they do the job. I used them mainly to modify the Reaper miniatures (saw off weapons and other small parts) and sometimes for other purposes of creating a miniature landscape. The knife set I received looks exactly like the picture. I didn't count them so I have no idea how many I got, but my set wasn't rusty. These things break very easily, but I've never worked with jewelry saws, so I'm not sure if that's normal. I can only imagine that these blades will be extremely troublesome for anyone planning to use this tool many times or trying to use it for its intended purpose. If I were one of those people and bought these discs I would give them a 1 or 0 rating if possible. On the other hand, if you plan on sawing soft metal occasionally (6 or 7 times a year) and don't want to invest a lot of money in something you don't intend to use that often, you might want to try this. Additionally, if you use them for miniature wargames, you can get crafty and recycle your broken saws.
