Hey Guys, just me showing one possibility to make a hammer eye punch. I used C60 tool steel in 20mm round stock: Here are the different steps: 1. forge the round bar to an octagonal shape 2. create a teardrop shape about 1 inch below the top 3. create a light taper that starts of at the end of the teardrop and gets thicker for about 2 - 3 inches 4. then cut off additional 4 inches and create a light taper that gets thinner to the tip 5. taper about 1 - 2 inches at the tip thinner than the rest 6. planish and make everything nice and straight 7. dress the striking face 8. dress the surface of the rest of the tool and remove remaining sharp corners (optional) 9. heat up the whole tool above the transition point and let cool down slow (eg. in sand or on coals) to anneal it 10. grind the tip 11. heat up about 1 inch of the tip to cherry red colour and quench it in water or in oil to harden it (optional) ATTENTION: NEVER harden the striking face!!! 12. temper the hardened portion and a bit above to sky blue colour 13. clean it and touch up the edge 14. look out for cracks, test whether it is shatter proof 15. have fun with it :). Here is the one I made in the video: Well I hope this was helpfull. Yours - Daniel
