A special guillotine for veneer. But those are hard to find. A razor knife is best for home use.

Put it in boiling water for about 20 minutes. That will allow you to bend it more. Bend the veneer to the position you want and allow it to dry like that. (Wait until it's very dry before gluing it.)

Veneer typically requires a protective coating to enhance durability and appearance. Polyurethane is commonly used for this purpose, providing a clear, hard finish that safeguards the Veneer against moisture and wear.
