How about this knife?
Or this cake slicing kit?
I think the Wusthof knife looks like a good one for what you want. I also like the knife that comes with the Zenker slicing kit. When I saw the images for that knife that was exactly the kind of shallow serrations I had in mind that I mentioned in my previous post. I don’t have one of those slicer kits, so I hesitate to say good or bad things about it, but I will say that the one concern I would have about it is how many layers will you actually get from your cake using it, especially if you tried stacking two or three layers on cake in it at once. Obviously stacking a layer on top of another layer means there will already be a space between those layers, so what happens if that space does not line up with one of the grooves to place the knife? You would have two really thin layers (the top from one layer of cake and the bottom from the other layer) that aren’t as thick as the other layers in the cake. I don’t know if this is making any sense the way I have this written, but I’ve always wondered about this when I’ve seen products like this before. Anyway, I hope you find something that works for you. Good luck and let us know what you decide.
I think the Wusthof 12 inch cake slicer has the same blade as the one Hector posted. It looks really good.
The Zenker kit is really more than I need since I have never torted a cake.
I ordered the Ateco but I can refuse the package when it gets here if I change my mind.
