Do your self a favor and look at some flint knapping videos on pressure flaking , you'll pitch that little brass hammer in the scrap metal pile. I was to blunt and apologize for being rude, the video is well made but the technique can be greatly improved on.
I really did mean half of it's life. Look at the length of the flint before and after the hammer treatment!
With pressure flaking you will be able to keep the edge straight across, lower or elevate it without flipping the bevel and only remove a fraction of flint that the hammer did . You won't knock the corners off either.
I really like the looks and performance of the round face lock by Kibler!
