Hello again helpful GURPS people!

I've been doing more reading and working to get the foundation of my first GURPS Cyberpunk campaign put together, and I ran into a bit of a conundrum. When players are putting together their characters, are there any rules about how implanted weapons differ from weapons used normally? Like if a player wanted to use a mono-wire whip that costs $5,000, would there be a different cost for having it implanted in their hand? Or if there's a chip they could get that allows them to use a power like the sandevistan, I don't know how to handle that since powers are point buy but it would also cost money...? I've tried looking in the books for any rules or recommendations, but if they exist then I think I've missed them.
