Penguin Folding Pocket Knife, 3.06" Sandvik 14C28N Stonewash Blade EDC Knife, Black G10 Handle, Button Lock, Ceramic Ball Bearings, Reversible SS Deep Carry Clip

I've been a fan of the original QSP Penguin for a while, and this button lock version takes it to the next level. Out of the box, the knife was razor sharp and well-centered. The button lock mechanism is snappy, smooth, and has zero blade play—something you don’t always find at this price point. The sheepsfoot blade shape is perfect for everyday carry tasks like opening boxes, slicing food, or general utility work. I got the model with the micarta handle, and it feels great in hand—grippy without being too rough. The ergonomics are spot-on for my medium-sized hands. One of the best things about this knife is how fun it is to fidget with. The button lock makes one-handed open/close effortless, and the detent is tuned just right for flipping or thumb-studding. Pros: Smooth, secure button lock Excellent build quality and blade finish Great action and fidget factor Premium feel without a premium price Cons: Pocket clip is a bit tight out of the box Might be large for those who prefer smaller EDC knives If you're looking for a reliable, stylish, and fun-to-use everyday carry knife, the QSP Penguin Button Lock is hard to beat. It punches way above its weight.

I love this knife. I have the penguin button lock with the flipper tab and this simple liner lock and thumb stud is just as nice. Great feel, size and quality. Deployment acoustics and action is great. It’s been my first choice lately.

First quality knife I bought, Right out of the box hair shaving sharp. Had it about a month still cuts like butter. Size is good, enough blade to do what you need. Issues Jimping on flipper tab feels like theres burs on it, button lock feels too shallow like the button is just barely disengaging feels like 1 or 2mm longer would be the difference.

The button lock action is a little sluggish out of the box. This is due to the spring QSP is using for the button lock mechanism. It is strong! It does start to break in after a day or two, and the action gets much better. The blade is riding on nylon caged multi row ceramic bearings, which you don’t really see on knives at this price. The blade is very sharp out of the box, with a very decent edge. Fit and finish is excellent, as well as build quality. You do have to apply a bit of force to the flipper to overcome that during spring, but nothing crazy. The thumb studs work perfectly, though. Overall, this is a great value for a quality pocket knife. If you like the Penguin, you’re probably going to love this one.

Really expected to like this, given that it had all the improvements I wanted in the standard QSP Penguin: flipper, button lock, ball-bearing pivot, G10 instead of micarta scales, 14C28N instead of D2. But the execution is lacking. First, the scales are fatter than the standard version (compare with my copper Penguin in the pics), so it feels chunky in your pocket. I could live with that, but the action (at least on my sample) was atrocious out of the box. Using the flipper, there was enough resistance in the pivot that about 30% of the time the knife didn't fully open and lock up. That's a major no-no. Likewise, the blade wouldn't drop shut when unlocked, even with the pivot so loose that there was blade play in the locked-up position. Disassembling, it appears the machining for the button lock mechanism and detent are just rough. No amount of lube or adjustment is going to fix the action here. Not at all what I expect from QSP, who generally punch way above their weight. By comparison, my regular Penguin with copper washer pivot is exponentially smoother. Stick with the regular Penguin. It's cheaper and still better.

Great knife for the price

This is my first purchase of a QSP knife. I'm impressed with the build quality and finish, especially for the price. The unique blade shape is great for opening boxes. Feels good in the hand. I've sharpened it to a razor edge. I look forward to seeing how it holds its edge.

I really didn’t believe in this statement until I bought one I am really impressed by the quality that QSP has in their knives It came really sharp I found this out the hard way The action is really good and the size is perfect for edc not too big not too small Easy to open with multiple ways to open and close with a smooth action button
