I have the Quen 4 bladed in white stagbone and the Queen 2 bladed in Cocobolo.
If I was still working as a carpenter and electrician, I would use the 4 bladed as my main work knife
One sheepsfoot I would use for marking out wood and stripping cable
The other sheepsfoot for food
A pen for small work, and the other for splinters!
If you want to use the 4 bladed for whittling, sharpen the blades differently
Of the pair, one set rough for fast removal, and the second set polished for fine work
The congress shape and size sits in my hand very comfortably for longer work like whittling
The sheepsfoot is quite narrow and slices very well
The pen is swedged nicely so you have a very strong point for fine work
I carry the two bladed version much more, it being slimmer. The wood makes for an even slimmer knife than bone.
Queen have the 2 bladed in Maple, which is a lovely wood.
Keep the Congress pattern, and exchange the 4 bladed for the 2 bladed?
