One thing I was just noticing... (not that it matters a whole lot)......
The 225 OT "son of a gun" has a liner lock for the saw blade. So, the frame must be like the 125 OT.
That is the only difference I see.

Here is a picture of my 225 OT.

STILL... that is a really beautiful knife!
two thumbs up!!
