At first sight those days, such a plastic thing can't be good. But... it is now in my toolbox for over 35 years and still stripping fine anything between 0.1mm2 and 2.5mm2. Only not pure PTFE (it flows too much). The Patent is over now and the design is widely copied by most major brands. My personal experience with the Knipex one is it stopped working after 5 years of use. Have no experience with the other brands. --- End quote --- This has me wondering. Who was the original manufacturer of this very tool. I have two identical ones from pre 1980. one labeled Paladin,and the other stripax. Can anybody find a patent? |

The first one I saw dated from the mid '70s and was labelled Stripax, at least here in Europe. This exactly was the same as the AMP I pictured. IMHO Stripax was taken over by AMP late '70 / early '80. I bought my AMP in 1981. I remember I was looking for a Stripax those days but it wasn't available any more. The representative came up with the AMP which was exactly the same thing. IMO those early ones outperform all the nowadays ones, apart from the specialised ones for very fine (PTFE isolation) wire. [Edit] Found this: http://www.heilind.com/marketing/documents/weidmuller-stripax.pdf Here the original is dated 1976. It is now a trade name of Weidmüller, but it is not clear who was first that came up with it. Because my original seems indestructible, has a wide range and also strips flat cable, I would go for a simple Weidmüller today. |

Do you know anything about Thomas&Betts? The ERG-1 WS looks the same as all the other modern ones. But I bought an older "ERG-1" from the widow of an EE the better part of 10 years ago, and it looks more like the Stipax/AMP you pictured, except even more primitive. It lacks of any of the ergonomic/organic curves, anyway. There's radiusing on the edges, but everything is basically a straight line. It says "made in England." I don't know how old it is, but other than some surface rust on the blades, it looks like it could have been made yesterday. It's as solid as a brick house. I'll update this with a pic in a bit; Photobucket is down for maintenance. I don't know if it's a "missing link" or maybe just an evolutionary side-branch/dead-end. But it could be interesting in the context of this thread. |

Their advertised auto adjustment feature :palm:. Also quality of the wire cutter is just crap. Edge of the one blade became as it was bitten even before I had a chance to cut a first wire with it. |

FWIW, I've noticed an increase of quality issues regarding Knipex products lately (pliers & cutters), but I figured they were an ODM'ed product from another manufacturer so wouldn't have been affected. :-// |
