To buy a stainless steel hive tool at my local suppliers is around Â£10 ($18 ).
I couldn't understand why they were so expensive, so got some of the guys in our engineering department to cut me two strips of stainless steel.
I then bent the ends using a vice.
The final stage was to add a "curve" to make it more comfortable for your hands to grip. I used an "angle-grinder" (or disc grinder perhaps in the US?), anyway, I marked a curve on using a lid from a honey bucket, and a marker pen, and then used the grinder to remove most of the waste. I finished up by using a bastard file (half round) to smooth out the inaccuracies caused by the grinder.
I them sprayed with some primer, some day-glo paint (so I can see them in the grass when I drop them!) and some laquer to provide a protective outer coat. I used a vibrating engraver to write my name on, so that at the club teaching apiary everyone knows who's they are (they get left behind, put in peoples pockets, dropped etc)
These are the finished products.
