I'm not going to harp on you for what your doing... I'v made many, many tools. Usually because I needed it NOW and couldn't get my hands on what I needed for several days. Usually, I ordered what I needed though unless I didn't think I would ever need one again.
I guess the only thing I have to say is they only cost about $20, why not just buy one?
I suggest this one. Lisle tools are good "cheap" tools.
