Guys, I got both the 4" and 6" today. FYI - I own almost all Cold Steel folders whether I can legally carry them or not. It's been a dry spell for a few months waiting on the 2018 releases, yes I know the Storm Cloud is out, but it hasn't floated by boat yet.
I'll call these 2 Luzons home runs but not grand slams! I love the look, the price, and quality on these 2 are fine. It's interesting that I played with the knives for a half hour before posting and didn't notice the rattle.
Pro:
-I LIKE the flipping action on both, its not a top ten flipper but I'm not at all disappointed. I've seen varying degrees of quality control from CS, so no surprise if your mileage varies.
-the liners are substantially milled out on both sizes - I am impressed.
-No sharp edges on the liners or flipper tab - I'm impressed as I've bought several $100-$250 knives with sharp corners on the liners.
-Thumb stud appears to be held on by a very tiny set screw on both models. They could have made it simpler but they didn't.
-Lockup on both knives is superb even without our beloved Triad lock.
-When flipping open the 6", it makes that "THWACK" sound just like a large Triad.
Observations:
-The 6 inch was sharper than the 4". Both cut standard office paper pretty well, but sharpness seems to be below normal for a new Cold Steel.
-On both of them, the safety slider button was marked up. It's either a manufacturing or handling issue or someone was playing with these knives before I got them.
-4" has the best feeling grip with a slight hot spot on the liner lock.
-6" offers many grip options, none are terrible but most are not particularly plesant. Best feel is a hammer or saber grip as far back as possible, choking up on the knife less pleasant.
-Interesting that the pivots appear to be the same size even though the 6" has enough material to make 3 or 4 4-inch models.
Cons:
-Again I'm not too keen on the 6" handle, but how can you complain about this monster of a knife at this low price?
-(Edit) the slider rattle - it doesn't bother me all that much.
Obsessing:
-I'm going to buy another 4" and cut/file off the tabs to make a modern traditional folder. Heck the fuller functions as a nail nick. I'm going to do it just because I thought of it!!!
-Okay Cold Steel, I'm waiting on the 5 inch and 3.25" versions with S35VN!
We're HOT for COLD Steel ;^)
