How to get a good spall

<< < (2/3) > >>

jamie:
PROTECT YOUR HAND :o. ie leather pad or glove

Hillbilly:
For spalling obsidian, I like a big, soft hammerstone. It's all about the angles, and like Eddie said-follow through is critical. Always hit a platform that is a less than 90 degree angle and below center line, and grind it good before you whack it. You want to use a glancing blow, not straight in.

Keenan:
Goos pics and description Hillbilly.
Thanks Jamie; Forgot to mention that ::)

Hillbilly:
Yeah, obsidian spalls coming off can remove important appendages.  :o

Justin Snyder:
