Of the 7 I bought for myself & 1 I purchased for my wife in the last year all have been excellent, with but one exception: the 4400-1 Casbah Automatic. Blade centering, grind & all that is perfect, the issue that I found with that particular knife is that it has a bit of blade play both laterally & vertically.
Really the amount of blade play is very little & what little amount of wiggle there is gets reduced 50% to 60% upon engaging the safety lock. Considering the Casbah model is a push-button automatic & doesn't feature the venerable AXIS lock, it's likely I'm just being nitpicky & looking to find fault with an otherwise great knife.
I'm what one might call "anal retentive" about that, though I find the term "particular" might be more accurate; so what bothers me might not be a big deal or it might not even perceptible or bothersome for someone else. To give you an idea, I let my knives break in before making any adjustments to the pivot & I will generally set my manual open knives to where it takes a tiny bit of movement to get the blade to close, but the blade will drop free by pulling the AXIS lock back.
As far as pocket clips go, the deep carry pocket clips can't be beat. Both the mini Grip I bought for my wife & the regular Griptitlan came with the same split-arrow pocket clip as the Northfork & I had Benchmade send me out a deep carry clip & hardware for both, satin for the Mrs. (cause she likes the 'shiny' clip) & black oxide for mine. She says her mini Grip rides much better in the front "pocket" of her jeans, if they can be called pockets. I don't carry my Griptillian everyday, it's more my task/hard use knife, but when I do carry it in my off-hand pocket, it is much more natural feeling & discreet. Plus it doesn't look like a the side of my pants grew a metal penis, so that's a plus.
The mini deep carry is very nice, it came on the Knife Works Exclusive Grizzly Ridge that my wife bought me for Christmas.
