Read this link and if you still have questions, I'll be happy to answer them.
This is from a supplier of all kinds of ground straps;

Why use COPPER GROUND STRAP?
Because of the “skin effect”, radio frequency currents tend to
conduct along the surface of a conductor rather than through
the middle. Because of this effect, COPPER STRAP is more
efficient than wire at handling high frequency currents. This
makes COPPER STRAP a logical choice in RF grounding
applications and in applications requiring bonding and grounding
for lightning protection. The rapidly pulsating DC currents
encountered during a lightning strike can be compared to high
level RF currents. COPPER STRAP handles these currents
more effectively than the same amount of copper in wire form.

Here would be a wrist strap if you want to go that way, other wise you could make one like I describe in the other link above.
