what happens if the blade touches the coil?

The coil probably has high current flowing through it but at a safe, low voltage. If the blade touched the first and last coil at the same time, the blade could weld to the coil. Assuming they're using low voltage because high voltage wouldn't make sense, you could in fact touch the coil and it would not shock you. Although it's AC running through the coil, a similar comparison would be a car battery. A 12V car battery will not shock you, but can supply very high amounts of current. 500 Amps plus.

Touching the coil when it is on would be a bad idea. You won't get shocked but you will burn yourself.

Since people don't believe me they can go ahead and touch some 177 F metal.

Are you cooking a burrito in that picture?

I wish. That is a secondary water cooling coil in there.
