Thanks for the replies chaps.

I've made reasonable hand axes and arrow heads in the past but gun flints, although they might look simple, are a skill level above mine. You really need to be proficient with blade cores and also I understand that the best flint is becoming harder to obtain.

it still doesn't quite seem right to be carting flint across the Atlantic and then bringing it all the way back again. That said, I can't seem to find anyone in the UK who admits to making gun flints at present. Even Will isn't advertising although I've not asked him.

So, If you are thinking of placing an order with your friend Tac, I would gladly join you.

Steve.
