Just unpacked my "pound of musket flints" from IMA. Forty- two genuine antique musket flints exactly as promised. I paid the extra few bucks for hand-selected. 38 are usable, most really well made, in various shades and shapes. When I checked other sources for flints, these are much cheaper but some are HUGE, too big for even my Brown Bess lock. I'm an admitted "napper", not a "knapper". Ideas on how to make little flints out of big ones? Simply?
