I love my Hoffi. Like Sam, I use it in my style of forging, not Uri's.
For those who don't want to spend the big bucks for a Hoffi - cutting the end of a 3-4 pound cross pein hammer down, and spending less than an hour on the grinder ,will make a pretty good copy.
First, cut the handle off and drill the wood out of the hole.
Using your metal cutting band saw, shorten the maul end by half its length, and shorten the pein to make it a much blunter drawing fuller. Grind all this to the shape desired, rounding the edges slightly. Sand the faces to 400 grit.
Reinstall the handle, making it short and fat.
I've done a couple of these , and they work well.
While on the subject, remember that you can take a double ended maul from HF and cut the ends to any shape you wish on your band saw. Cross pein, vertical pein, angle pein....etc.
