I have the
4300 CLA, the
5400 Serum and the assisted version of the APB
6800.
The
CLA is really sweet.
The newer version with the green/black G10 handle is very slim, great for in your pocket carry.
Great lock up with an adjustable stop pin, great blade style and size.....awesome knife.
The
Serum is really cool.
This knife has dual functions, it's an Auto & a Manual.
Manual: Opening and closing can be done like any other axis lock knife.
Automatic: Open by pulling the AXIS lock rearward until automatic opening mechanism activates.
You need to pull the axis bar very purposefully to activate the auto function.
It's not something that can be done accidentally.
It is extremely cool.
The
APB is pretty cool too.
This ones cool because it is still truly an axis lock knife; however the axis lock is hidden under the scales and the knife operates with the simple push of the button(s).
Super easy.
I have de-assisted mine.
This is very fun to play with and is easier than the standard axis to operate.
I have all three and would not hesitate to recommend any one of them.
My fav has probably got to be the
CLA.
It's so so slim and the scales are so so awesome.
I could be slightly bias though, seeing I have a thing for knives with cool scales.
