The top tool is the Siemon S66BT.
It has two cavities, one for 66 block terminals that are 0.038" thick and another for 0.045" think.
The rotatable bar has one end for cutting wire and the other end for not cutting.
I've set it up for 0.038" thick terminals (that's what's on the 66M1-50 split block) and for cutting wire.
When the blade is removed the handle will swivel open and there's a slot to store a spare blade.
The other tool is the Commercial Electric 898 110 sold by Home Depot.
It comes with a 110 tool that can be reversed, one end for cutting wire and the other for not cutting wire.
There is a hole in the handle to store another blade.
