This may be my oldest handmade sculpting tool.
I made it when I was around 18 years old.
The blade was forged on my homemade brake drum forge out of an old saw blade.
The Osage Orange handle came from a fallen tree in Texas. The rivets are brass rod. The branded GDO logo was hand " carved" from a piece of aluminum scrap.
Why? I had little $ and specialized tools weren't available. And why not order off internet... It wouldn't exist for decades :-)
