It was still NEVER stated that the two pieces of the Bo that appeared when Lily called on her weapon were intended to be Tonfa.  Yes, we saw that they were the same design of Theo's Tonfa, but they were never said to be Tonfa, nor were we led believe that Lily would ever use them as Tonfa.  Again, as far as we saw from the first episode, they are ONLY intended to be combined into the Bo, therefore stating that they are also Tonfa would be speculation.  I have started a formal discussion of this on the Jungle Fury article's discussion page.  If you have any concerns, address them there so everyone can see and offer their own opinions should they have any.
