All that cost savings goes out the window the first time you get sued ;) But also keep in mind that test fingers are used for more than just seeing if it can poke through a screen. Way way way back when I worked in the auto supplier industry, we needed to test to make sure the auto-up windows and auto-closing minivan doors would actually not cut your finger/hand/leg off. We always used pencils as a first try. They break a lot easier than a dowel rod of the same diameter. If we were happy with the results, we'd get out the test finger. If it looked a little iffy, we'd suggest that the engineers should use their own fingers if they were really confident in their work.
