I am an ice skate technician, who does equipment repairs for ice skates. An "old hand" mentor of mine showed me a piece of leather he said is known as "skate leather," and is used for repairing various parts of ice hockey skates. Now I'm sure that's just what they called it, and there's no specific designation or type of leather for it.
He didn't have a source for acquiring any.
Could anyone recommend a type of leather that would have excellent toughness properties, resistant to excessive stretching, is not too thick, and can be folded and conform to contours of the skate. An example for its use would be in the lacing area of a skate when an eyelet rips out. The fix would be to cut a piece of the leather to fit the area, the internal reinforcement cut out and replaced, the leather patch folded over and sewn through. Then new eyelets punched.
Thank you for your input!
