The number 7 jointer plane!
The no 7 is also an excellent plane to use with a shooting board to accurately 'shoot' (trim) edges of components square and straight.
Of course it's perfect for planing long straight boards to form a strong glue joint hence the name 'jointer plane'.
I have two of these planes, the first is a 1960's Stanley Bailey no7 which is my day to day go to plane for general use at the bench and for rare trips on site.
The other plane is a very well built Clifton No7 made in Sheffield. This is an even heavier plane than the Stanley, matched with a thick blade this plane is used for finer and more accurate work.
