>>Rather than flints glued to a popsickle stick, someone here not long ago talked about superglueing them into the channel of a house key blank. <br><br>That's a great idea.<br><br>I'm teaching a Wilderness First Aid course in 2 weeks time - that would be a great (and cheap ;-) keepsake to hand out to the students. I remember you used to be able to get key blanks in bright metallic colours, although it was actually just a regular key with a coloured metallic coating. Can you still buy these? Would Crazy Glue hold on them, or would I be better off just getting a plain key?<br><br>On second thought, why don't I just buy one and try it out? (Experimentation - what a concept. :-)
