The Cold Steel 4Max Scout 

Thank you for showing one-handed operation & blade thickness. CS claims 4.8mm, USA sellers claim 1.8mm, obviously it's closer to 5 than 2.

Liners are made of stainless Steel not aluminium.

Just impulse bought one of these 😅

My original, Italian made 4 Max uses S35VN blade steel, Titanium handle liners, and grey G10 handle scales. And yes I carry lots of 4” blades but quickly learned that even the AD10 gets put way down my list for it’s shear bulk in the pocket...

SR-1 & SR-1 Lite are not thicker than 4-Max... They are all the same thickness.

Ultimate Hunter and 4-MAX Elite both have S35VN blade, not S45VN.
