I found that every single plastic balisong I have bought bounced a little more than I liked. I found every one needed just a little more weight on the handles for my taste. I found that even a single ball - one of the bb's, does make a large difference in the way they move. I needed just a little more weight. They make a difference - and especially help the swing of plastic balisongs.

It felt amazing when I got it and you can use the picture for the website.But overall I love it and you could work on the threads cap but is amazing

I have these caps on every one of my balisongs I am actively flipping. I keep 15 of them right next to me - they all have Zippy Caps. It is the perfect thing to add just a little extra stop - so when it goes to slip out of your hand, the cap - allows you to catch it. Plus when you drop it - which I do my fair share... it doesn't damage the bali. I have dropped them on concrete, pavement, gravel, ceramic tile - chipped a little off the body - but before I had these I did damage a couple of them pretty bad - where these caps would have protected them. Plus the colors - just look cool. Recommend to anyone who likes to do a little customizing. If you have a large collection, like I do, it really adds just that little extra bit - of cool. These things are great - in every color.

These inserts are so cool, to be able to dress up your balisong collection by purchasing some colored inserts for trainers is too cool. The blue matches my Revo nearly exactly - I think it looks very good. The inserts went in without a hitch, fit perfectly - and do not slip. Adding a spice of color to your collection, really upgrades it in my opinion. Highly recommended for anyone that likes to do a little customizing. Definitely worth it, I'd recommend them to anyone.

These inserts are so cool, to be able to dress up your balisong collection by purchasing some colored inserts for trainers is too cool. This is one of my favorite balisongs to flip, and I like it even more with the matching inserts and caps. It sure dresses it up, is easy to install - and stays in place. I would recommend this to anyone that is looking for a quick way to upgrade your collecction. Highly recommended!

These inserts are so cool, to be able to dress up your balisong collection by purchasing some colored inserts for trainers is too cool. With this one, since I had a 2 color balisong, I elected to go with 2 colors - made it a little more expensive, but I think the results are astonishing. This is one of my favorites, because of the dual color - and no way near my most expensive. I absolutely love the inserts for this balisong. I would recommend them to anyone. They just look great!

These inserts for the Krake Raken fit perfectly, most with an easy press, the black was a little harder to get in there, but after working it some, it went perfect. The red - slipped in much easier and neither have ever started to move - they are definitely in place.

Love these, they fit and stay on. I like how you can get a ton of different colors. I put two on my CF Lucha to give me extra grip at the bottom of the handles because the CF isn’t very grippy.

Great product, love them. Great that you can mix and match colors. If you get separate colors you don’t need a bit handle indicator. If you get the same color I put an indicator on. But some knives don’t have enough room for both. Would be nice if there was an option for a black ring or dot so you can get the same color and don’t need a separate bite handle indicator. Also, make sure to check the size chart, these don’t fit on every knife. But the stay on and keep my handles from taking damage and look super cool.

First I was surprised how well they flipped once installed. Initially I didn’t believe these were going to be any good. They were very light out of the box. I added all the tungsten balls and it is very neutral. I think because I used the heavier CF blade. Fans go forever on the initial twirl, but you can’t keep them going because the blade and handles are so balanced. I will likely put a regular Lucha blade on it in the future. I’m not planning on doing any cutting with it, but I understand why he says this isn’t designed for that. They are light with a little flex and do sound like plastic straws banging together when flipping. I’m not a sound snob so that doesn’t bother me. Overall very nice for what they are and way better than the stock heavy steel handles. Would be nice if in the future these were made with a thin aluminum liner and add less/ or no tungsten balls. But I like these any would recommend them.

Adds protection and flair. Quality.

Makes the knife extra flippy. Quality product. Feels totally new, looks great.

I like

This mod literally fixed the whole issue I had with my kraken trainer v3. Not to mention it looks so cool. It really makes my kraken feel personalized. If not for this mod I would’ve definitely sold my kraken❤️‍🩹

Works as advertised, sounds very nice with no ring
