KK02BK Titanium Flipper Pocket Knife, Quick Open Keychain Folding Knife with #24 Replaceable Blades for Everyday Carry

The build quality feels solid and the action isn't too tight or loose. The flipper opens the blade smoothly, though it does take two motions with the first flip only opening the knife to the half way point. It's very smooth, but the blade is so light and the tab so small that even pressing the tab fast and hard only opens it half way, and then you can pull / flick down on the back of the blade and it opens the rest of the way. The blades that come with it are nice and sharp, though you can get any other #24 blades you prefer. I have the kk01 and I think it fits in my hand a bit nicer than this kk02 since it's a bit longer, but overall I prefer how much easier it is to open this kk02 with one hand using the flipper tab.

Knife come with plenty of replacement blades which are easy to replace and very sharp. Titanium shell and steel construction is of great quality and the compact designs is ideal for a keychain or pocket. 10/10 would buy again.

Nice light weight and compact. 75% cheaper than the one I saw off TikTok. Glad I got this. Doesn’t flip open as nice as I would’ve expected but that’s alright.

As advertised and works well. For those who want replaceable blades and a small pocket profile, this fits, and is well-made. Wish for two enhancements: 0.25 inch longer handle to take #36 blade without mod and a liner lock would add to it even though the slip-joint works just fine.

Very well built. Has awesome fit and finish. Blades lock in very tight. Be careful stupid sharp.

More or less misleading product information. The "shell" of this knife is titanium, but the shank for the blade, internal lock spring, and hardware is all steel. The knife, while sleek, is therefore very heavy for it's size. Overall good quality but I wish it was made fully of titanium to be lighter. Included blades are sharp as can be. Easy to swap blades out.

Lots of ferrous metal components

The blade pops out almost every time I've used it. I've cut myself twice because the blade came out. Both times I was opening a package... cutting packing tape, not something hard or beyond this little knife's capabilities. And yes, I had the blade installed correctly. It's a shame, because the quality is very high. Apart from the blade popping out 1 in every 5 times you use it. Disappointed. Wouldn't recommend to anyone.
