I've never used one of these, but here's a video of another make showing the dings made by the jaws:

I think you'd be needing quite a bit of wood filler.

Cheers guys.
I will be protecting the board where the tool pivots, that a definite. I have found the promo vid for the tool now and it looks quite good, although it doesn't show what state it leaves the wood in.NEW Bahco Nail Puller - YouTube

I think I will buy it as it will come in handy and its only £30.

Plan A is to shimmy under the floor from the under stairs cupboard where a big hatch is anyway. If I cant squeeze my 14 stone past the gas and electric incomers, or the sleeper walls don't run in my favour, then its lifting the lovely floor up.

This vid shows a bit more of the damaged caused Andy
