Anne, there's a lot to be said for big hydraulic bolt cutters and even more for the (incredibly hard to find) explosive guillotine cutters, powered by a 12-guage shell.
But some of the new battery powered tools are *not* the toys of 25 years ago.
I'm just saying, they add another choice to what is and was available.
As to the safety
of any power tool, and the collateral damage from using it improperly, well, isn't that why you have to labor with bolt cutters instead of just wrapping some detcord around the part and blowing it apart in one shot?
An unparalleled tool, that you are most unlikely to find in any chandlery
