well i was messing around with a bic  multi color pen and tried it as as wacky tool it worked great and well it was  free  laying in junk draw .just  take it apart and use the lower tube part/ worm fits in great ,hope this tip  helps out   ,,,,orings i got from nappa auto parts  

joez---You might try Lowes/Home Depot for the o-rings.  Here they are much cheaper than at the Auto Parts stores.  Lowes has them in the Plumbing section.

I can't believe Yamamoto hasn't come out with a $50 tool to get those split rings on their baits seeing as they are basically the only ones you need them on.  Personally, I'll stick with the ones that don't need "tools and accessories".  I think the BaitMonkey worked on this one with Gary,...the 2 were in cohoots

;D

LBH, I agree.  I get between 2 and 3 times the use from a wacky since switching from GY to ***.
