I recently purchased the Channellock 349 Lineman's Pliers. In the picture it is shown laying next to the Kleins that I've had for about 6 years. I've mainly used the Kleins for cutting copper wire, which is their intended purpose, but I've also cut some nails with them as well on occasion. Ive been very pleased with the performance of the Kleins and really didn't need a replacement.
There are, however certain tools I like having a duplicate of for various reasons. After a fair amount of research I decided on the Channellock 349 model since I've heard they are the most durable lineman's pliers that Channellock makes. Based on the design and the great experience Ive had with the brand in the past I'd expect them to last a very long time. Channellock also sells the 369 model and variants which is priced significantly less than both of the pliers in the picture. I don't doubt the 369 is also good but the reviews I've seen indicate the 349 is the best. Time will tell but so far I'm pleased.
