What kind of tools are these?

Hi,
First three pics are one tool. The last is another tool.
Anyone know what they are called and what they are used for?
Thanks

The second tool looks like a crimper of some sort. Maybe to crimp lugs to wires. Looks similar to this crimper: http://tinyurl.com/agoujo4

The first tool looks like a clamping tool. Not sure though. Very cool!

Looks like high quality wire stripers...

Neither of the above....

#1 is  Bell System "B" Crimper - "B" Sleeve wire crimper and Holster. Crimping tool was used for cable splicing and supposedly gave a better connection than soldered - For B style beanies. Beanies are little white connectors which go onto a twisted pair of wires, and the crimper presses in the sides to make a good connection. These were used a lot during the 70s. The beanie is inserted into the slot of the crimper, the handles are depressed to crimp it exactly the right amount.

I have the other one in the museum, but old-timers is getting to me not having its numbers - I will get back to you on the other... I think this is called a reversible lineman sleeve twister/crimper (most often made by Klein), but I will have to look at mine.  Each side holds one wire...

It could also be a Lindstrom Sleeve Twister, which looks very similar to the Klein tools:

Last photo, B crimps.

cool! the "B" crimps are still used.... I see them on discount low voltage.com and other telecom/networking sites. the tools are still usable!

Yes, they are still useable, but they aren't as popular as they once were, as connectors like the Scotch-locs give a better connection over time with their gel filling and don't require stripping of the wire....

One of the first jobs I had was installing a step system in my former high school, and most connections were made with B connectors. This would have been around '73.
