I had a bunch that he sent me- I think I sold or gave them all away- I don't think I have any left.
I had tried to use them, but in the end I realized that in many cases the teeth are too aggressive to be used easily be hand as they are meant to be used in machines.
They were a fantastic idea, but if you ever try to do it I suggest sticking to less aggressive saw blades. Your hands and arms will thank you for it.
