This is well worth the money
James Z. on Dec 27, 2016

So this was a Christmas gift from my parents, it flipped amazing right out of the box. Loctite soon after you first get it, latches are amazing, i am a young child and getting used to flipping something so large and light took a while, not long though. Also what I found weird was that I got a different shaped blade than the picture. I love it though and it looks like the alpha beast. I don't know though, I am a fetus child and I don't know that much XD

Great for average Use, 10/10 Service!
Michael G. on Oct 4, 2017

I would have given this 3 or 4 stars as the tang pin came out in a couple days and I lost it, but I gave it 5 because when I contacted them, they sent me a new one, free of charge.

The best
The G. on May 25, 2020

It flips well. And has good balance. And the price is cheap.

It's 'health insurance'
Steven R. on Dec 29, 2018

It's quality is good, though more expensive than some trainers. But look at it like 'health (and ego) insurance'. When the blade raps you on your fingers you're NOT paying a Doc. for stitches and you are NOT explaining "I was playing with a knife"!

Great for every day use
Cody m. on Aug 1, 2017

Iv had this trainer for several months. I have 3 other trainers also and a few nice knives. But this thing is what goes with me most places. Took my latch off day one. And this is the only trainer that has held up to all the abuse of daily flipping. Rollovers are nice, chaplains go great, twirling is fun. But fanning can be a bit off due to the weight. Overall a great buy though!

Bear Ops listens!
Mark G. on Dec 2, 2018

I ordered this Balisong trainer to . . . well . . . learn (play) with a butterfly knife. After reading the reviews from many trainers I decided to go with the Bear Ops. It's a bit more pricey than other trainers but the quality is second to none! Some critics commented on the quality of the G10 scales - mine were in great shape with no edges that needed to be addressed. Some critics commented on the wear of the G10 scales at the pivot points. I see Bear Ops have added what I would call Oil impregnated brass bearings (I don't know if this is the case for sure but IMHO it appears that way). I DO agree you need to disassemble the pivot screw assemblies and re-secure them with Loctite Blue to the point where you have the freedom of motion you desire. Would I buy or recommend them? OH HELL YES!!!!

Good for the price
gevin m. on Jan 26, 2018

Have owned this for about a month. out of the box the fit and finish was a tad rough in some spots but its a trainer i planned on beating it up. i scuffed the handles up with a green scrubby pad to soften them up out of the box. you should also oil this out of the box mine got pretty squeeky pretty fast. aside from that its a great flipper that does not break the bank. i have a pinned construction style trainer that i cant tighten and that drives me crazy and the extra $40.00 is well worth it for this one pros- well constructed good beginner flipper adjustable pivots looks nice cons- gets dirty very easily needs to be tightened every day depending on use handles are pretty rough out of the box

pretty good one as my first butterfly knife
PU D. on Aug 21, 2019

Really good one as the cheap alternative for Benchmade butterfly knife. Also a good one for the butterfly freshman. It is a lot of fun to practice with it. However, the rotation is not as smooth as I expect. And the lubricant on the blade makes the scale looks dirty, wondering if anyone can give me some suggestion about how to clean it.

Hayden T. on Feb 20, 2016

As soon as I picked this trainer up, I could tell it was infinitely better than the crappy $15 trainer I bought off amazon. Despite a few cosmetic blemishes, this trainer is amazing. I would recommend this to anyone. EDIT: It definitely needs some loctite, as the pivots are coming loose

decent overall great for the price
christian a. on Feb 6, 2017

Great for when flipping an actual blade isn't practical or acceptable. Not gonna lie it feels cheap when you first flip it. But for the money its pretty decent. Redoing the tread locker is a must and actually wait for it to cure or it will fall right apart. Handles are a bit grip happy but you get use to it. My only concerns are the tang cups getting over worn from the lack of liners, they dent in pretty good. G10 vs metal its expected. Overall for what you get id say its well worth it. And i got the B2010R4P instead B201B4P with my order don't know why but the OR4P blade looks way better Anyways IMO so i'm not complaining.

Best trainer thus far! (edit: but falling apart now :( )
albert t. on Mar 7, 2016

This trainer is a lot better than CCC trainers you get from amazon. Though it is 2 to 3 times the cost of some of those, it survives a whole lot better from drops onto concrete floors and extended flipping (my CCC trainers lasted two days at most before it starts getting a lot of bladeplay/tang pin issues). Secondly, it looks a LOT more tame than some of the other trainers. I don't get a second look at work when i'm flipping this. A few drawbacks straight from the box are: 1) a bit stiff - had to oil it and flip it a while to loosen up, 2) not the best QC - tang pin is a bit marred but functional on my copy. I cant complain tho; i love this thing and have no fear of droppin' it - it's a true beater trainer. edit: i've been flipping this a ton for the past three weeks and the G10 handles around the pivot are starting to grind away :( i can see why some steel liners can help prevent this from happening. I'll still keep flipping it but it'll be inevitable that the handles will break :( Wondering if others are experiencing the same thing?

flips ok but...
Nick V. on Apr 15, 2016

I ordered the Bear Ops B-200 from Blade HQ have been very happy with it. I bought this trainer thinking it was going to be the same but the handles are different sizes and weight. The safe handle is about 35% slimmer than the bite handle and I can definitely notice it in the feel and balance when flipping. i wasn't too bothered by it at first but when I flip it for some time then go back to the B-200 it's like flipping a completely different bali when the whole point of this trainer was to be identical to it's bladed counterpart.

The pivots are coming loose
Hebin T. on Jan 25, 2019

This knife looks beautiful, but after half an hour of playing, it began to loosen and make metal rubbing sounds. If you don't care about it, its price is good, but I prefer Boker's butterfly knife trainer,they have the same price. It's a good trainer, but for me, it doesn't seem to fit me very well.

Second one
Joseph E. on Jun 2, 2019

I purchased a second one of these after TSA stole my original. I loved the original one a lot. The new one I received was a downgrade. After one week of flipping the tang pins bent and fell out. I bent them back and replaced them but the new tang pins they are using are not worth the buy.

Don't take apart
brice c. on Jun 7, 2016

This balisong is awesome, when I got it out of the box it flipped amazingly, but when I took it apart (like a dumbass) I striped most some of the screws. Eventually with enough loctite the Bali would hold together but In the end I just duct taped the handle scales together. But then I figured if I went latchless I could move the screw and pivot that holds the latch together to the safe handle it would hold together. All together this trainer 4/5 stars if you don't take it apart. Sure the tang cups will wear out and the blade will touch the spacers but a little duct tape can fix that. Just remember, don't take apart your bear and sons balis. Oh and the pocket clip doesn't work it screws on to the scale in a particular way that it bows to far upward.

Modded Mine
Chris M. on Jan 2, 2020

As it is stock, I would give it 2 stars as there is better out there and it was just not that great. However, if you take it apart an refinish the handles, you improve it a lot. I modded mine to accept 316 stainless bushings..... This trainer is awesome with bushings even untuned. It went from zero to hero with the bushings. This trainer of mine has received hours upon hours of abuse and drops on concrete everyday at work(6+ hours a day). My main complaint is the tang pins. The threaded type of tang pins are inherently inferior to the press fit pins, and this trainer makes that statement true.(one had a clean snap from a drop to concrete) I would give them more props if Bear and Son's website worked enough for me to buy their spare hardware and tang pins, but alas the website sucks for purchases, as I want it to go to a PO Box. Things I personally would change from stock. -remove textured grip. -press fit the pins. -either change the blade style to something more reminiscent of a blade, or add something to one side to distinguish the bite and safe sides. -make a premium version with bushings. -use pivot barrels for the spacers instead of tapping directly into the spacer. -forget about having a latch. Positives -It has a neutral and slightly handle bias balance on a light knife. -It's price still get you something to work with that is made in America. -Decent customer service. -Parts are available unlike other companies. I do sometimes prefer flipping this over my other higher end knives, mostly because of its weight. It carries its weight very nicely and can flip at great speeds, while staying balanced. I wish they made a bladed version with bright colored g10, and a non powder coated blade. This has the potential of being THE 100 dollar knife that everyone will get.

Not good
Jeremy K. on Nov 1, 2021

Torque bolts starting falling out minutes after starting use. Applied red lock tight, waited for 12 hrs and used for about 1hr before others starting falling out. Would not recommend for the price.
