About JJ Stone Craft


JJ Heo is a Vancouver-based artist and knife maker. Inspired by the ancient art of flintknapping, JJ began making obsidian knives and has honed his skills for over 12 years. Each knife is handcrafted and designed by JJ and his family, and is a symbol of Vancouver's rich history and culture.


Our knives are made of obsidian found in the Cascade Range of North America. Each knife is handcrafted using an ancient technique called flintknapping, a survival skill passed down by our ancestors in the Stone Age, when it was used to create hunting tools such as arrowheads and hand axes. After nearly 3 million years, this skill has been transformed into an art, and is still used to create tools by traditional knife makers and within Native American cultures. 

All knives are made using obsidian stone. Handles are commonly made of antler, cactus, animal jaw, bone, horn, and wood - all sourced legally from Canadian hunters. Wooden handles are decorated with handmade carvings of images representing Vancouver and its diverse culture.

Obsidian is volcanic rock formed from cooled lava. Often called volcanic glass, it is hard and brittle, and is one of the sharpest objects on earth. Though originally used by cavemen to create hunting tools such as knives and arrowheads, it is still used today to create surgical scalpels and skinning knives.
