After 5 years of experience with this tool I can confidently recommend you to BUY this tool NOW. LOT.It has a strong grip for jerking and left-handed movements. It's even durable and heavy enough that I've used it as a light hammer. If you're really desperate, you can use a band clamp to turn it into a ghetto vise. This is another one of those tools you NEED NOW, but that's another story. The handles are comfortable, non-slip and easy to clean. This is very important in order to grab everything you need with maximum strength. Speaking of strength, the 12-inch tool was the perfect length for me. I never wanted less or more. For me it is the perfect compromise between mobility, hard-to-reach places and robustness. Keep the channels clean and lubricated and the tool slides in and out perfectly. The teeth are perfectly positioned for gripping and walking. And hardened steel is STRONG. It will rip copper to shreds if you're not careful. Which product is A+ from a company from USA. BUY ONE NOW!
