<p>My "useless" screwdriver I made in metalworking class consisted of steel or iron rod that I heated in a forge. While hot, I hammered one end flat and then ground it into final shape. This was then reheated and then quenched in water to temper it. For the
handle, I placed the rod with the finished blade in a sand mold with a space to pour molten aluminum to fill out the handle. Finally I ground the rough edges of the mold seam off the handle.<o:p></o:p></p>
<p>Viola! A pry bar that thinks it is a screwdriver :)<o:p></o:p></p>

<p>Happy memories! At my middle school in the mid-80s we did exactly the same thing as Oren, though we went a step further by turning the cast handle down in a lathe then knurling it. The results were actually quite attractive and I still have mine somewhere.
Metalwork was proper hands-on in those days, training us (you might say) for jobs which no longer existed.<o:p></o:p></p>
<p>Going well OT, the pinnacle of metalwork classes at that school was the building of a Mamod-style steam engine from scratch. As I went up through the school, I watched the final-year students running their engines up and down the corridor outside the metalwork
room and yearned to build my own.<o:p></o:p></p>
<p>(Only recently, I discovered that the engine design almost certainly came from this 1972 book:<br>
<a href="https://www.camdenmin.co.uk/collections/engineering-practice-skills/products/step-by-step-metalwork-3">https://www.camdenmin.co.uk/collections/engineering-practice-skills/products/step-by-step-metalwork-3</a><br>
)<o:p></o:p></p>
<p>Of course, just as I reached my penultimate year, the powers-that-be realised that nobody needed hands-on metalwork skills any more and totally rejigged the curriculum to concentrate on design skills. No more steam engines. I was gutted, and it still rankles
nearly forty years later ;-) Perhaps I should buy that book...<o:p></o:p></p>
