I have a few Kershaws, and I usually carry one in my EDC rotation.
The Blur is really nice.
Pros:
Well constructed with no play.
Razor sharp out the box.
Very strong locking mechanism. It quite surprised me infact how well it worked
Smooth assisted opening. It doesn't rip itself out your hand like some brands.
Super grippy. Avoid the older inserts that were like sandpaper like material and look for the rubber like inserts. Far easier on your pockets.
Cons:
A little large and heavy, especially for smaller hands. Sometimes I like a little smaller blade for more delicate stuff.
The Leek is a thing of wonder. I had the stainless steel, the smoky blue and now the rainbow leek.
Pros:
It is very nicely sized for my hands
The assisted opening works very well.
The blade shape is perfect for me to opening annoying sealed plastic baggies
Nice and thin so it rides great in the pocket
Cons:
The Stainless and Rainbow versions can be a little slippery on the handle. Of course the G10 handled version solves that.
The locking mechanism isn't as tough, nor is the blade so it not a heavy duty EDC knife.
The blade is very pointy, so if you abuse it badly, you might snap the point off the end like you would with most other blades.
Kershaw Skyline. I cheaper economical knife. It has no assisted opening, but what you do get is hard to beat in the low end market.
Pros:
G10 handle that is nicely shaped for gripping.
Decent blade design
Cons: I don't care for the flipper only design that sometimes rarely does not lock up properly.
I am on the market still for a decent price JYD II so I will see about that. Would love an Avalanche too.
