I am just wondering how to figure out if a hook has a japanned finish on it. I know there are different ways to blacken hooks but I have no experience in this area. I bought some Partridge blind eye hooks off a guy and he wasn't sure about the finish. He did say that they were definitly made some time prior to Mustad buying Partridge. So they are hooks made in the Redditch factory just not sure when. Did Partridge make 6/0, 7/0 and 8/0 blind eye hooks right up until Mustad bought them? Does Mustad still make these hooks today? I have done alot of searching on the internet and can't come up with much info at all. Any info you have would be appreciated. Thanks in advance.
