How do you smoke your flake?

[Pipe Smoker]

I always cut my flakes into squares. About 3/16" on a side.

Edit: My tobacco knife is a small 5" santoku that I bought at my grocery store for $6. It has a slight, constant-curve convex edge. Also came with a plastic sheath. It's the best tobacco knife that I've ever found. I use it against a small bamboo cutting board, dedicated to tobacco.
