First of all, ordering from EDC Knives, Duane was a real pleasure to deal with, and calmed all my nerves about ordering this knife. He answered my email within the hour and was polite and to the point.
Needless to say, I will be ordering from them again.

As for the Tri-Folder, it came in a black nylon pouch. Said pouch has a velcro closure system, and a belt loop for horizontal carry.
The knife itself rests VERY low in the pouch, with only about .25 inches exposed when fully seated. There is room for the knife to stick out more, so if you do decide to use the pouch, stuffing it will be a must.
It's also worth noting that the belt loop on the pouch in quite skinny. Anything much wider than the average leather belt will not fit through the belt loop.

Numerical stats on the blade, taken from EDC Knives are as follows:
440C Blade
Blade length of 2-3/4"
4-7/8" closed and 7-7/8" open in overall length
9/16" thick at the widest part
2.8 oz in weight

On top of all that, the entire construction of the knife is stainless steel, from the handles to the pins. Quality on the knife I received are better than expected. I was thinking that this would be an interesting knife to play with, but I can definitely see this knife going places with me, where my Cold Steel Spartan is not appropriate.

On first inspection, I can see the pivot pins clearly. They've been ground flush, and don't move, but I think that the people who mass produce this knife could have done a better job at hiding the pins for aesthetic reasons.

On the opposite side, you see a divot for a retention stub. It seems that unlike the earlier models of the Fred Perrin Tri-Folder, this version CANNOT be deployed without first getting over that initial friction. If held horizontally with the opening down, the arm and blade do not deploy. I'm debating whether I want to file the nub down or not.

The lockup on the blade is decent. when closed, it's perfect, but when open, the blade allows the inner handle to rest recessed into the main handle, providing a small amount of room for the blade and such to wiggle. A go with a dremel or something similar will remedy this problem in no time. I might also try adding extra meat to the area of the blade where it meets the back of the main handle. The manufacturer ground down that specific spot for the blade to rest deeper into the handle, but perhaps ground too much or shouldn't have ground that area down at all. I think that by adding material there, the blade would not have this problem.
There is also a fair amount of lateral play to the knife. Perhaps avoidable with better tolerances, but it's not enough to detract anything from the knife in my eyes.

When deployed, the blade faces outward like most knives do. Just be careful not to ride the edge on the main handle while opening, and not to smash the tip into the handle. The latter happened to me, and even though it was a fairly light tap, the tip did indeed get slightly deformed and rolled over.

When closed, the blade in locking into a position where the sharp end cannot contact the handle. I was worried about this the most. didn't want a knife that would beat itself up just because it was closed. It does however rattle side to side.

Overall, for a few dollars over $50 shipped, I'm pleased with my purchase.
Fun to flip, useful for everyday tasks, and looks great. It does acquire fingerprints quite easily though, but that's to be expected.
If you're looking for a different kind of folder that still gets the job done, then the Fred Perrin Tri-Folder might be the knife for you.

If anyone has any further questions, or comments of any kind, please feel free to let me know and I will respond to them as best I can in a timely manner!
 
The only difference I see between mine and yours is that the divot on mine is so small, it has no effect on the blade dropping open. Nice toy!
 
Thanks everyone
:)

Also to note, I mistakenly thought that the nylon pouch could only be worn horizontally.
It can infact be worn vertically as well, and when vertical, there is more room for a bigger belt. It fits over my Tan Riggers Belt for my ACU's with room to spare.

It's also worth noting that there was some minor friction issues with the main handle and the minor handle rubbing on each other, hindering smooth deployment. With some pliers and a cloth, I bent the bottom on the second handle close to the pivot together, and fixed the problem.

Once I file down the nub, I'm thinking about either tightening the pivot down to reduce slop on the second handle, or shim it. If regular washers are too thick, I will cut small washers out of coke cans! Hopefully I can fit some PB in there.

Thanks again for the encouraging words!
 
I have a knock off made many years ago and I loved it .What a great slicer and fun as hell to play with but super loud. I made a small piece of plastic about as thick as a credit card and glued it into the upper groove in the handle to make sure the tip didn`t hit the inside of the steel handle it worked well .You have made me wonder what I did with it I will have to look for mine now. Also mine didn`t have anthing to keep it closed or open .
 
It has been quite a while, and I have some updates!

The stock main pivot that comes on the Tri-Folder has no type of thread sealant to prevent it from wiggling itself loose!
It is also made from sub-par steel, I have sheered off the head of the pivot... Not to worry though! Replacing it with the 5/32" pivot from Knife Kits was quick and painless! I also like this pivot better, it's smaller and sleeker looking in my opinion.

A drop of loctite and the pivot moves no more!

Adding a strip of an old credit card or something similar to the spine works flawlessly, any accidental tip smashing now does no damage to the blade!

The overall blade handle does acquire scratches a little easier than I would have liked, it's got light scratching all over now, and some noticable scratching in high traffic areas.

Overall, still a great little folder I think, does the job well, gets the odd look and nice compliments, and is quite nice to use!
Still very happy with my purchase, and still carry it to this day!
 
This knife looks exactly like a knife I got in San Francisco's Chinatown a few years ago for about $7. Very slim, unique, not very sturdy at all. Quick to flip open and closed. Definitely a "gravity knife" in any jurisdiction that prohibits them. Fun toy.

Doesn't sound to me like its a gravity knife. Not if it has a detente to keep it closed.
 
The knife I have, and I can't say that it's identical to the one in this thread, though it appears to function identically, is designed to be opened with a flip of the wrist. There is no thumb stud, nail nick, button, lever, etc. Just flick your wrist and it's open. A knife designed to be opened that way (a much simpler movement than a balisong) is, I believe, a gravity knife by definition. Mine is locked away in storage or I'd put up some pictures or a video. With a little bit of practice it would open with a flick in any direction.
