No, they are ONE PIECE.

"The Ball Peen Hammers have bonded and molded Shock Reduction Grip® which offers the utmost in both comfort and durability, while reducing vibrations caused by impact. Estwing hammers are the only hammers that can make this claim. The head and handles are fully polished and are forged in one piece."
Same with their other hammers:

Their picks, drilling hammers, engineer hammers, welding hammers, all ONE-PIECE. That's the reason I bought them in the first place.
Dude, he's not arguing that they're seperate pieces
What he's saying is that Estwing didn't forge the hammer from the beginning as one piece. A head and handle were forged seperately, and then at some point, were all meltified together to become one piece.
The statement that they're "forged in one piece" sounds misleading - kinda like "they were forged into one piece."
I'd be real interested to see their manufacture process if they started life as one piece, because I didn't think that was possible, given how the head has to be done all special.
