I work with a lot of rawhide. cut strings for braiding and will cut from 1-2 foot squares. I will then roll the squares in wet towels. they will take 4 hours to 24 hours to become ready to cut , depending on the thickness of the hide.
I cut off the tines to 2-5 inches and put an eye screw in the top and then tie a good rawhide knot , attache a key ring and sell them for key chains. some ladies like the longer ones for protection.
