star wars - Why don't non-Jedi carry lightsabers as tools?

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.

And in 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.

[reasons why this is not a duplicate]

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.

[later]

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.

Here is Mark Hammil saying that "definitely" non-Jedis could use lightsabers.

Answer

I think the key issue is acquiring a lightsaber in the first place. Before the Great Jedi Purge there were many Jedi and therefore many lightsabers, but a Jedi would have to lose his lightsaber for a non-Jedi to acquire it -- and any Jedi who lost his lightsaber would try to recover it. After the Great Jedi Purge there were far fewer Jedi and therefore far fewer lightsabers.

The only other way to acquire a lightsaber would be to construct it yourself, but it may be necessary to use to Force to construct one. Even if you don't need to Force to construct one it's probably more difficult to do so than it's worth.
