Quick Answer
To create a composite tool from rawhide, start by selecting a suitable rawhide material, then create a series of sinew strands and soak them in a mixture of animal fat and plant resin. Next, shape the rawhide to the desired form and attach the sinew strands using a technique called 'lashing.' Finally, use additional sinew or plant fiber to reinforce the tool.
Preparing the Rawhide
Begin by selecting a thick, flexible piece of rawhide from an animal such as a cow or deer. Cut the rawhide into a suitable length and shape, depending on the tool you want to create. A good starting point is to create a rectangular or oval shape, about 1-2 inches wide and 6-8 inches long.
Creating Sinew Strands
To create the sinew strands, take a length of cordage sinew and soak it in a mixture of animal fat and plant resin. A good ratio is to use equal parts of fat and resin, mixed with a small amount of water. Let the sinew soak for at least 30 minutes to allow the resin to penetrate the fibers. Then, use a sharp knife or stone to cut the sinew into individual strands, about 1/8 inch in diameter.
Assembling the Tool
To assemble the tool, use the lashing technique to attach the sinew strands to the rawhide. Start by making a series of small holes in the rawhide using a sharp awl or needle. Then, thread a sinew strand through one of the holes and use a small amount of plant resin to secure it in place. Continue this process, working your way around the rawhide, until the sinew strands are evenly spaced and securely attached. Finally, use additional sinew or plant fiber to reinforce the tool and give it strength and durability.
