I am going to order a custom Zulu bladed pocket knife. I can get almost any length I want, but am undecided between a 4" and smaller 3 1/2" (ish) blade.
I would appreciate anyone's opinion if you have or used a Zulu pocket knife.

This is too complicated a question
Unfortunately I don't have a Zulu. But the Zulu is very similar to the standard Victorinox Alox blade. I like the standard blade size of 70mm, my friend would like one closer to 4, but they don't make them like that. Another friend of mine would like to have a 3.5 blade, but he lives in England where blades longer than 3 inches can be confiscated by the police
