I have the same green QSP Penguin. Got it from Drop. But mine has a very weak detent and the blade easily falls open, so I’ve never carried it. Don’t want to reach into my pocket and get surprised by a sharp blade.
I also have this knife and mine is decent. Like some other people here, I got it on Drop when the price was irresistible.
Remember that things can go wrong in production. Every once in a while, a lemon can squeak its way through Quality Control. That seems more common in this tier of budget knives. Besides trying lots of different budget knives for myself, they tend to be my default gift for others (in addition to flashlights). I inspect, clean, and lube every single one of them including disassembly whenever possible. I've seen issues with QSP, Ganzo, CJRB, Tangram, and even Kizer's Vanguard line. If it's something I can fix myself, I do. Otherwise, I contact the company. Most of the time, they want to make it right. So if adjusting the pivot tension doesn't work, contact QSP.
I have about 14 mora knives. I bought different color ones and made a display rack . The 4 or 5 I actually use are sharp and so far indestructible.
Since I have OCD I have to buy multiples of everything. Watches, guns , knives , gas masks , swords , medieval helmets , flashlights , guitars (I can’t hardly play) whatever .
I have a bunch of models as well. The only one I found lacking was the fracture which was not very sharp on arrival. I tried to strop it and it got worse, so I had to sharpen it on a stone, a skill which I’m still not very good at. It’s a little better now but I havent used it, kinda bought it on a whim since it was so cheap at $30.
I did have an elementum with a stripped pocket clip screw and the clip would move out of place, was able to order some new screws from them and I loctited them in so it’s good now.
Really like the Ortis, very solid and low cost. it has a similar blade shape to the Dogma, but Dogma has better closing action.
It was about $48-52 at FastTech and had been as low as $40 on Amazon at one point.
It shows its unavailable to me on Amazon, maybe they don’t send knives here or something.
I actually ended up buying it after telling myself I wouldn’t because it’s too much, with 10% GST (tax) it ended up costing about US$80 which is a lot more than I wanted to pay.
Some of those Steel Will knives look very interesting however shipping from the US is a deal killer, plus taxes and currency conversion. I just found they don’t ship to Australia as well trying to see what the total would be.
Anything from the US is pretty much out of the question though as most places charge $50+ just for shipping to Aus.
I ended up getting a few of the Tonife Squirrel knives as well just for small tasks, the company that owns Harnds owns Tonife as well.
I emailed Harnds and have found out Flyer Industrial Co. Is the parent company and aside from making Harnds and Tonife they also manufacture CRKT, Boker and others. They said Simlar knives they OEM for US companies sell for $150+ just due to branding.
He also mentioned that the Desert Fox was such a popular knife that they are considering bringing it back next year using a different steel.
Anyway, I spent about x4 as much as I intended to on knives (I originally only wanted 1) so that will have to do for a long while.
I broke my favourite knife earlier this year and have been looking for something to replace it ever since so this will be an excellent replacement I’m sure.
I thought I remember a few folks looking for this. TwoSun TS128-S90V is back in stock at White Mountain Knives. $99 Free shipping too. Nice for the US folks not wanting to wait on overseas shipping.
Anyways, it’s marketed as an outdoor knife. I’d prefer 8Cr13Mov to D2 in wet or humid conditions.
Also 8Cr should be easier to resharpen with simple tools like a flat stone if there’s nothing else at hand.
I have been reviewing Chinese knives for over 5 years, always from good Chinese brands, on my blog and YouTube channel, and one thing I recommend is that you always buy from reputable and revised Chinese brands, so that you do not get a bad surprise.
You can see some of my reviews and they can help you in these purchases.
Seller on Ebay has a 2pc lot of new Sanrenmu 710’s for $29, free shipping. I have a few of these and they are very nice little frame locks if you don’t mind tip down carry.
