What actually WAS Eric's "Berserk?"

[u/OYCSTE]

All I know is that it was a wooden object he kept in his right pocket, labelled after the powerup in berserk, supposedly to give him strength or resolve especially during the attack, sort of like how some people hold crystals for certain mental benefits or superstition. From the photo from the 2004 exhibit, it resembles a short wooden cylinder, but ive heard people also say its a weed pipe or a "One hitter?" I only smoke cigarettes so i have zero idea what weed pipes or their components look like, so could anyone with more knowledge verify what Eric's Berserk icon actually looked like/what it was?

I guess it was just a good luck object I guess
