I am a huge fan of the old Wagtail combo, I don't think they make them any more so I guard my two like gold.
With the combo, I can do the whole of the insides of a large pub/restaurant with one fill of my B.O.B.
Glyn at Omnipole had some, I bought my last one from him.
The combo is a single pass tool, it has a pad made of the same stuff they use for paint pads, and the blade is a centimeter behind it. The handle swivels left to right so it's very easy on the wrist.
Without doubt the best bit of trad gear I ever used.
