[size 4][font "Times New Roman"][#0000ff]I am thinking it is not about metric system which is looks much more convenient for me.
Numbering like ...#6,#8,#4,#2,#1,1/0,2/0,3/0,... has some advantages vs. numbering from 1,2 and up, because make it possible to introduce a new sizes of hooks or threads in both directions: smaller and bigger.
Theoretically could exist hooks small like #20 or smaller. With system from 1,2,3.... how you will designate hooks smaller then #1? In fractions or negative? It is also not convenient.[/#0000ff][/font][/size]
