The tools are the same.
An awful lot of Inletting can be done with just a few tools, it's the carving that'll make you want a more diverse set.
But I have seen tutorials and videos where one guy will use 4 tools and the next has a list of about 30.
You can inlet locks, side plates, ramrod pipes and install butt plates with
1/4" chisel
1/16" chisel
#6/6mm and #10/6mm gouges
and an Xacto knife
start getting into the carving and a series of shallower gouges and various curve shapes help a lot.
I just picked up this affordable set, the tools take a sharp edge easy enough and fit well in my club mitts;

But I have 8 other tools that I picked up as needed through the years.
It's a good idea to look around youtube for tutorials, the Library for some books, all to get an idea not only what's needed but to see different techniques.
Your going to make a few mistakes, there is a learning curve. I chose to just be happy with basic inletting for years, and just keep trying new things as the need comes along.
