Sharp bend in the tickler

How do I achieve one of those lovely looking points in the tickler? Is the only way to set up a forge and hammer it in? Also what is the purpose of such a feature? is it a primitive safety feature to avoid accidental shooting if the bow was layed down while cocked?

The sharp-pointed bend in medieval crossbows is usually found in 15th and 16th century German or central european crossbows.  When I forged my own triggers, it was always a real pain to make those... Yes, I used a forge, but a good welding torch will work as well.  Eventually I realized I had a conveniently hungry armorer-friend who was happy to make such triggers for only slightly more than the standard Western type, that have slightly rounded 90 degree angles, rather than a point.  So the easy way is: get a picture of what you want, find a smith or armorer, give him 25-30 bucks, then collect the trigger when it is done. 
Why did they make them that way?  I have no idea... seems to serve no real purpose, save maybe a hook to hang your bow up, but it looks pretty cool.  Geezer.
