Extra Sinew Spool

Honoring our namesake, we proudly give back to our community by supporting and donating to local pet shelters and dog rescues.

Every hide we use is a direct byproduct of the beef industry, helping keep over two billion pounds of waste out of American landfills each year.

We source leathers from award-winning tanneries committed to resource conservation, organic recycling, and clean vegetable-tanning methods.
