A Knack for Knapping

Arkansas group keeps ancient art of flintknapping alive using native stone.

By Heather Iacobacci-Miller

If you’ve ever seen an arrowhead and wondered how it was crafted, then you’ve already been introduced to “flintknapping.” However, flintknapping is more than just shaping stone. It’s the ancient craft of shaping stone into tools and points — like arrowheads, spear points, and knives — by striking and pressure-flaking along natural fracture lines. It demands precision more than force, with each flake removed intentionally to create a sharp, controlled edge. For modern practitioners, the process is as important as the finished piece. It’s about the hands-on way of understanding how people once worked with stone, and how that relationship to the physical environment and their craft tells a story of humanity’s history and our place in the world.

Arkansas is central to that story. The state’s abundance of knappable stone, especially novaculite from the Ouachita Mountains, made what we now call Arkansan an important material source for Indigenous toolmakers for thousands of years. (The word “flint” in flintknapping is more of a catchall for a variety of stones used, such as chert, obsidian, novaculite, and quartzite, not just flint.)

Phil Iacobacci, Hot Springs resident and avid flintknapper, says, “The novaculite that is found in our state is some of the finest material to work with.” While noting that not all of it is useful as a tool (as is the case with all workable stones), the region sports an abundance of stone that meets flintknapping’s exacting criteria — clean, free of fractures, and large enough to work down into a tool — and the same stone that drew our ancient ancestors continues to draw knappers today, with present-day gatherings connecting modern flintknappers to a much deeper history that is rooted in the land itself.

Phil — who happens to be my father as well as an ace flintknapper — is an avid outdoorsman with a deep respect for nature. He has been drawn to the water, the woods, and the history of those who cultivated the earth long before us for his entire life. He grew up walking the shores of Lake Ouachita with his parents, who taught him how to spot arrowheads and other Native American relics. He feels a connection to the Native people, their love and respect for the land and nature. He is a man of many hobbies, enjoying learning traditional crafts like woodworking, carving, and, of course, flintknapping.

The First Strike

I recently sat down with Phil to talk about his passion for flintknapping and meeting up with like-minded hobbyists for group flintknapping sessions, or “knap-ins,” to gain a better understanding of what flintknapping is and the importance of knap-ins in passing down the craft to future generations.

At any knap-in, the sound comes first. Not a crack or a snap, but a sharp, precise tick. It repeats across the knap-in, each strike quick and deliberate. It’s not long before the ground is scattered with flakes that catch the light like broken glass. Some knappers work in silence, others talk without looking up, their hands moving steadily, practiced. “If the strike is solid, it will snap, sharp and clear,” Phil said. When a strike is wrong, the sound gives it away: too dull and too heavy, crushing … and a wasted shard drops to the ground.

However, no one judges because failure is expected; it’s part of the learning process. While tips and advice might be given, even in a group, the real exchange isn’t between people, but between hands and stone, carried out in controlled movements refined through repetition. For flintknapping enthusiasts, that sound doesn’t stop. It’s the same note that’s been ringing out for thousands of years, still shaping stone, still gathering people together as a community.

“The connection to our past is a must for us to move forward in life. We must understand the past to become a better world and a better person.”

Learning the Craft: Patience and Failure

Learning flintknapping is an exercise in patience with a steep learning curve and the understanding that you will make mistakes. Phil explains, “It’s the mistakes that lead you to be a better knapper. If you don’t make mistakes, you’re not learning. You study that mistake and figure out what you did wrong, not what you did right.”

“Learn from that mistake and put it into the locker of ‘the oops, well that didn’t work’,” he continues. “One must always have those lockers to become a better knapper.”

Safe to say, early attempts tend to produce more shards than tools. Progress comes slowly, measured less in finished points than in the ability to read the stone and recognize where it will break cleanly and where it won’t. When asked how long it took before his work began to feel intentional rather than experimental, Phil says, “That part of the path came slowly for me and in rather awkward progress. More failures than I’d like to admit. The process was a slow but rewarding journey, still one that I am walking.” 

At a knap-in, your learning curve is on open display, something you must be comfortable with. “When someone makes a mistake, you can rest assured that person will hear it from everyone, but all in fun, of course,” Phil mentions. But this is a time when beginners can sit beside experienced knappers, watching techniques passed quietly from one set of hands to another. Advice is offered when asked, often demonstrated rather than explained. Over time, individual styles emerge, shaped by experience and preference, but the fundamentals remain the same. It’s in this shared space that the craft continues, sustained by people willing to fail repeatedly to get one strike just right.

Community in the Chips and Shards

Flintknapping is a social craft, and knap-ins are an important part of passing the craft down to future generations. People gather, visit, watch demonstrations, and work on their own points. These knap-ins help keep the craft alive. They’re also vital to sharing the valued knowledge from an experienced knapper to a novice.

“It’s hard to just watch a video and be able to understand all the steps that go into making a point,” says Phil. “Hands-on is the only way to understand just how it all works.”

Phil shared a bit about some action challenges that knappers often do during knap-ins. It’s all in fun, but also a learning experience as well. One such challenge is when the group uses one chunk of stone to start, and each person strikes it one time. Once the knapper makes their strike, it’s passed on to the next person. The challenge is in making sure you pay attention to the previous strikes and discern where you can or can’t make your strike, so you’re not the one to end up snapping or shattering the piece.

Knap-ins are also a way to enjoy being in nature, just as our ancestors did. Phil noted that most knap-ins are outside under shades or pavilions. He made an important observation: When making a point, there’s a lot of dust, so being outside where the dust can disperse is ideal.

Flintknapping as Living History

The art of flintknapping isn’t about recreating the past. It’s about listening and learning from it. Flintknapping connects us to Indigenous history. Phil believes that “the connection to our past is a must for us to move forward in life. We must understand the past to become a better world and a better person.”

For many modern knappers, flintknapping is best understood as living history rooted in Indigenous knowledge and traditions that long predate the gatherings seen today. The craft itself carries a lineage tied to Native peoples who shaped stone for survival, trade, and culture, and contemporary practitioners are careful to acknowledge that inheritance rather than claim it as their own.

Demonstrations at museums, public events, and knap-ins are often framed as education, not reenactment, with an emphasis on respect for the original makers and the landscapes they worked. For modern flintknappers, it’s preserving history, not claiming it. Phil said, “Our goal is to pass along our knowledge of the art, and by sharing the history, we will be able to preserve the history and art.” So, it’s in these settings that the focus shifts from finished points to the act of teaching and showing younger generations how stone breaks, how patience matters, and how paying attention to the material can open a small but meaningful window into the past.

Keeping the Craft Alive

Keeping flintknapping alive isn’t about preserving a technique for its own sake. It’s about maintaining a relationship with material, place, and time, a lived-in relationship of the type that is increasingly rare. In a world shaped by speed and convenience, the act of working stone demands the opposite: patience, attention, and an acceptance of failure as part of the process. Each broken point and clean strike reinforces the same lesson: Nothing worthwhile comes without listening closely to the material in front of you.

In Arkansas, that connection feels especially grounded. The stone comes from the land, the gatherings happen outdoors, and the knowledge is shared face-to-face. What’s passed along isn’t just how to strike a rock, but how to slow down, how to observe, and how to respect the people who first learned these skills thousands of years ago. Phil says that he feels there is a renewed interest in traditional crafts more recently, saying that “people are, for the most part, wanting to understand the past and learn about our history, about the people before us and their way of life.”

As long as hands continue to meet stone at knap-ins, museums, and informal circles, flintknapping remains what it has always been: a living craft, shaped by history and carried forward, one careful strike at a time.
