25 seems kinda steep.
The last two standard issue 110s I bought came out of the box only slightly sharper than a brick. The first I sharpened with the 30 degree setting (15 per side) on the Sharpmaker. That worked out very well, that knife is a mean slicer and at that angle it keeps the edge pretty well.
The other one I reprofiled on some x-coarse stones and then freehand sharpened well below 15 degrees. It's probably somewhere between 10 and 12. It's an effective slicer, but the blade stock is really too thick to support that angle for very long.
