How would pinchers have to evolve to better manipulate tools?

+0
−0

I'm thinking about an alien race that evolved from large terrestrial crustaceans and has developed a somewhat large brain. Like crabs on earth, these creatures have pinchers wich they use for self defence and picking food, but they also use them to move around sticks and rocks to build a small nest for their young. Now, I'm thinking that this species becomes sentient in the far future and starts developing civilization. There's a problem though. To my knowledge, in order for a species to develop civilization it needs to be able to manipulate tools easily, either through the use of hands with a prehensile thumb or maybe a tentacle. But crabs pinchers have very little mobility outher that opening and closing. How could pinchers evolve in order to better manipulate objects in their environment?
