I think that's best. More generally, if it's too hard to cut easily with either a serrated knife or a sharp knife, use a saw.

Given that you'd have 3 fingers below the blade, it might be awkward to use with a block/board on a table. Anyway, keeping the saw blade that far from the block/board would stop you from going close to cutting all the way through - better to just saw on top of something you don't mind cutting into (or on a glass board, if you don't mind blunting the saw a bit).

Saws like this are for field use by hunters. The stop on the end of the saw blade is so that you don't pull the saw past the bone (I think these are pull saws, so this is useful).
