Round used saw blades (san francisco)

Looking for used round saw blades like from Skill saws, table saws, chop saws, etc.
Different sizes OK.
Don't need them to be sharp to cut.
I use them for different (art) projects.
Metal blades only.
Need 10" and up.
Band saw blades are good.
Sawzall blades and even Jigsaw blades.
The more old, worn and crappy looking the better.
Big teeth on the blades preferred.
Be a recycler and instead of throwing them in the garbage, give them to me.
I pick up in SF, Brisbane, SSF, San Bruno.
Thanks a lot.
