These tools make a lot of sense to electrify, though the fishing rod is pushing it... But flint is an *entirely* nonrenewable resource as of version 1.81 without further mods.
And, surely a "lossless" mode on the mining laser is a reasonable request? Combat with it makes quite a few holes atm, unless you use the one-block setting, but at that point it is just better to use a stone sword!
