A person could always correct the lack of a 4.5 or 5.5 by buying a single one somewhere for not a lot of money, problem solved if it is an issue.. I am more interested in the steel most say S2 steel, but some claim theirs is better. I guess it is the care and method of hardening and tempering the steel that makes a difference.
But it wouldn't be a Snap on. Checking my latest current catalog, #1400, there is no 4.5, or 5.5 (or 3 or 9) of the type shown offered. Skipping sizes
Buying one tool at a time gets VERY expensive.
Some sizes get used very little. But there is nothing more frustrating than not having the right tool when needed.
