If lightsabers can cut through anything, why don't more people (especially bounty hunters) carry lightsabers as a simple cutting tool?
It has been proven here why non-Jedi don't carry lightsabers as weapons.
However, this questions asks whether there are non-weapon items based on lightsaber technology.
But my question is different: If a non-Jedi can get ahold of a lightsaber, such as Boba-Fett, Grievous or Cad-Bane (the latter two who have used them as weapons, in fact), for example, why doesn't he keep one handy? It doesn't take Jedi training to use one safely in order to cut things. Han Solo has done it on occasion (on Hoth, for example, when he opened the TaunTaun) and didn't think twice about it.
The Force Awakens, Finn easily used a lightsaber without any training whatsoever, so it's not a matter of possessing the Force that makes the item able to be used.

This question was marked as a duplicate of this:
Are there non-weapon items in the Star Wars universe based on lightsaber technology? However, just from the title you can see the scope is different. Perhaps there are non-weapon tools based on lightsaber technology, but my question is whether non-Jedi carry lightsabers, it has nothing to do with non-weapon, non-lightsaber tools.
Some of the replies below maintain that non-Jedi people cannot carry a lightsaber because of various reasons. It seems to me that Jedi would certainly be more skilled with a lightsaber on account of their affinity with the force and the relation of the force to the kyber crystal, but other people could definitely use a lightsaber as a tool.
