I'm a little concerned. Someone in a previous posts was saying something like Inno tapered blades are different than other companies tapered blade. Does that mean the tenons are different size? I have a Inno Roberts Pro Tapered blade. Will that fit in any tapered shaft? or only Inno tapered shafts? I wanted to put it into a synergy II shaft or a broken SL shaft. Will it fit snugly? Any help is appreciated
