try just flipping flint around at about 10 shots or so. bevel up/down.i sometimes just hold frizzen and let the hammer down and push against the frizzen with flint.i dont think i ever tap my flints,i just flip em until to small to hold.secret is to have flint flat and not that hunchback on it. thats were mizzy wheel as rb and cayugug comes in real handy.
