I have an old 1971 made Uberti 1858 Remington with 5 Very stuck nipples. I tried soaking in Kroll. No luck. Then i soaked in Liquid Wrench penetrating oil and i even put an old nipple wrench on and smacked it with a hammer some. Still no luck. So, which is the strongest most durable nipple wrench? The Ted Cash ratcheting or the Slix Shot T. Or some other? I already rounded the edges on a Traditions T and a Track Of The Wolf T.
