OKA Factory was founded in 2007 by Mr. Koji Oka. As a handmade leather enthusiast, he deeply understood the importance of “good tools” and was determined to create a series of high-quality leather tools that were different from conventional ones, repeatedly improved to make them easier and more comfortable to use.

OKA Factory’s products are grouped into four categories, including hand-stitching tools such as chisels, leather carving and stamping tools and hardware installation tools. Their knives, in particular, are highly popular and well-loved by customers in Japan and overseas.

Since 2020, Leatherism has been the official distributor of OKA Factory tools in all categories. Products are available for retail in-store and online, and wholesale for industry partners and collaborators are welcome. For inquiries, please contact us by email or WhatsApp.
