Are you complete without a Sgian Dubh?

[MacMillan of Rathdown]

I do happen to have a shillelagh that my mother brought back to the States after living in Ireland for a while. Don't know if it's a proper eveningwear shillelagh, though.
I'm wondering how wide the handle and the blade of a sgian dubh is? I think I have all the other measurements.

Picking one up at random the measurements are as follows:

Overall length (tip of blade to top of pommel): 6-5/8 inches;
Length of grip (tip of pommel to base of blade): 3-1/4 inches;
Width of grip (at base): 1-1/8 inches;
Width of grip (at pommel): 1-1/16 inches;
Thickness of grip (average along length of grip): 5/16-inch;
Width of blade (at grip): 1-1/16 inches.

Hope that answers your questions!
