Recently on my trip while browsing through a hobby shop, I came across these nifty little tools. They are made by Royal Models, (their Part No.66). The steel photo etch sheet consists of 19 different "tool" shapes/pieces that can be formed and bent as needed and used in your standard #11 0r #2 Xacto blade handle.
The instruction/backing sheet shows some of the potential uses, but upon carefully studying the tools one can see many more uses/options for them. They cost me 9 Euro (about $13)......and in my opinion were worth the cost (as the time it would take me to make them myself out of brass would cost me much more.)
[These are made by the same company that makes the photo etch saws listed here in a nother thread.]
