Sam Andrews has a great method for sure. I use scalpels with #11, 23, 25 blades. Far superior to exacto blades.
Cheap, super sharp and made for cutting flesh. Can be stropped for even better results.
I use scalpels.. Heck, that's what they are made for. Far superior to xacto blades and can be stropped for long life. And cheap! I ordered the plastic handles from amazon.
The #11, #23, #24. #25 blades work great!
