Thanks Cayugad for the response I have found alot of info on this subject by looking through all the posts i could find. I am a very experienced percussion shooter but flintlocks are a new deal for me. I want to drop a deer with a flintlock It's my last big challenge for myself. I used to walk behind my grandfather in pennsy when I was little but he's all gone now and that was 25 years ago. the reason for learning to knap is I want every chance that the guns goin off when I need it to and it would be helpful in the woods. Thanks for the picture. Will that tool work on store bought flints (cut) as well? I have some black english flints but I have so many cut ones too. nysb.
