People still run into a problem with Google transations. IT IS NOT A FLY ROD. IT IS HAE ROD, AS IS IN ROD FOR CATCHING HAE - which is a type of fish. Google translates hae (ハエ) as "fly" but in this context it doesn't mean fly. It means "pale chub." It is analogous to us saying a rod is a "trout rod." The Rinfu is a Pale Chub rod.
For most, if not all, Japanese characters there are two ways to pronounce the character. The explanation in the parenthesis tells you the correct pronunciation. The correct pronunciation is the Sagiri not the Hyakiri (which is the wrong pronunciation). Daiwa has discontinued the rod, and it is no longer available from Daiwa. A few shops here and there in Japan still had unsold rods in stock, which people bought and offered on eBay. Daiwa continues to list it in the catalog so the shops that still have them don't have to discount them as old, discontinued merchandise.
You can buy a Model T on eBay right now. Your neighborhood Ford dealer would tell you it isn't available if you walked in and wanted to buy one.
