In my experience control and precision with a cane is quite an art. The ability to target strikes and control force, to raise welts and weals and leave marks for a week or more without seriously broken skin or scarring is far from universal.

I wonder what percentage of US Dommes have this skill set? For those that don't is it because it is more of an English thing and not in as wide demand in the US?

Many Dommes include "canes" under Impact Play or CP in a laundry list of services offered but what are the signs one should look for that might indicant a highly skilled practitioner?
