Hi all, I have a set 3-SW of these irons I bought waaayyyy back in a secondhand golf shop on the outskirts of Chester. I'm having a garage clear out and they're just sat there gathering dust, I can't find anything out about them online ie if they're any good and or indeed worth anything so a Japanese Golf forum seems an ideal place to start. I don't just want to bin them if they could potentially partially finance a new set, but also don't want them to be sat there in perpetuity. Does anyone have any insight into them? Thanks Sam
